The ceramic disc brakes are, for example using a ceramic matrix composite material manufactured with a specific process. Some ceramics are semiconductors. Most of these are transition metal oxides that are II-VI semiconductors, such as zinc oxide. While there are prospects of mass-producing blue LEDs from zinc oxide, ceramicists are most interested in the electrical properties that show grain boundary effects. One of the most widely used of these is the varistor. These are devices that exhibit the property that resistance drops sharply at

the metal acts as the electrodes. The ceramic material is a mixture of finely ground granules of paraelectric or ferroelectric materials, modified by mixed oxides that are necessary to achieve the capacitor's desired characteristics. The electrical behavior of the ceramic material is divided into two stability classes: The great plasticity of ceramic raw material works well for many special applications and enables an enormous diversity of styles, shapes and great dimensional spread of ceramic capacitors. The smallest discrete capacitor, for instance, is a "01005" chip capacitor with the dimension of only 0.4 mm × 0.2 mm. The construction of ceramic

Bioceramic Bioceramics and bioglasses are ceramic materials that are biocompatible. Bioceramics are an important subset of biomaterials. Bioceramics range in biocompatibility from the ceramic oxides, which are inert in the body, to the other extreme of resorbable materials, which are eventually replaced by the body after they have assisted repair. Bioceramics are used in many types of medical procedures. Bioceramics are typically used as rigid materials in surgical implants, though some bioceramics are flexible. The ceramic materials used are not the same as porcelain type ceramic materials. Rather, bioceramics are closely related to either the body's own materials or are

are a few differences between these groups. The SiC group has over twice the fracture strength and thermal conductivity when compared to the oxides group. However, the oxides are more stable in combustion and oxidizing environments. The process by which the textile is impregnated depends on what materials will be used, as well as the intended purpose of that fabric. These fabrics are utilized for thermal, mechanical and electrical applications for a variety of reasons. Ceramic-impregnated fabrics are most importantly used in three main fields: aerospace, electronic, and industrial. In aerospace, the fabrics are used in space shuttles for the

Nano-ceramic particles embedded in a resin matrix, are less brittle and therefore less likely to crack, or chip, than all-ceramic indirect fillings; they absorb the shock of chewing more like natural teeth, and more like resin or gold fillings, than do ceramic fillings; and at the same time more resistant to wear than all-resin indirect fillings. These are available in blocks for use with CAD-CAM systems. Gold fillings have

Re-lining or lining treatments was used to added support to the original canvas until it was determined that it created more damage. Strip-lining is now used instead. Strip-lining involves reinforcing tacking that has weakened. Tears in the canvas are repaired with adhesive or sewing. Ceramics vary widely in their construction, style, and use. There are three types of ceramic objects. They are earthenware, stoneware, and porcelain. Each of these types of ceramic objects are fired at different degrees and

are some examples of what the application of ceramic chemistry can accomplish. In ceramic bodies the physical properties of the final fired product are often more related to the firing curve, the physical properties (e.g. particle size and shape, decomposition history) of the ingredient materials and the mineralogy and interaction between the different particle types. Ceramic chemistry Ceramic chemistry studies the relationship between the physical properties of fired ceramics and ceramic glazes and their chemistry.

Shaft Tombs and its offerings: One of the most representative characteristics of the culture are the shaft tombs, funeral chambers with access through a shaft, hence its name. Construction was normally made by digging on tepetate, with a depth varying depending on the soil hardness; sometimes with steps or a vertical circular duct, with a diameter of 1.20 to 1.40 m, used to reach one, two or three small chambers, resembling a baker's oven, where the offerings were placed next

See NIJ levels 3 and 4 for typical requirements for rifle resistant armor. Broadly rifle resistant armor is of three basic types: ceramic plate-based systems, steel plate with spall fragmentation protective coating, and hard fiber-based laminate systems.

multilayer capacitors with mostly alternating layers results in single capacitors connected in parallel. This configuration increases capacitance and decreases all losses and parasitic inductances. Ceramic capacitors are well-suited for high frequencies and high current pulse loads. Because the thickness of the ceramic dielectric layer can be easily controlled and produced by the desired application voltage, ceramic capacitors are available with rated voltages up to the 30 kV range. Some ceramic capacitors of special shapes and styles are used as capacitors for special applications, including RFI/EMI suppression capacitors for connection to supply mains, also known as safety capacitors, X2Y® and three-terminal

the range of frequencies, often an electrolytic capacitor is connected in parallel with a ceramic or film capacitor. Many new developments are targeted at reducing parasitic inductance (ESL). This increases the resonance frequency of the capacitor and, for example, can follow the constantly increasing switching speed of digital circuits. Miniaturization, especially in the SMD multilayer ceramic chip capacitors (MLCC), increases the resonance frequency. Parasitic inductance is further lowered by placing the electrodes on the longitudinal side of the chip instead of the lateral side. The "face-down" construction associated with multi-anode technology in tantalum electrolytic capacitors further reduced ESL. Capacitor families

ceramic parts are needed where the length to diameter ratio is very large, extrusion may be used. There are two types of ceramic extruders one being piston type with hydraulic force pushing a ram that in turn is pushing the ceramic through the loaded material cylinder to and through the die which forms the extrudate. The second type of extruder is a screw, or auger, type where a screw turns forcing the material to and through the die which again shapes the part. In both types of extrusion the raw material must be plasticized to allow and induce the flow

size of large-grained iron aluminides decreased during super plastic deformation. The properties of ceramic materials, like all materials, are dictated by the types of atoms present, the types of bonding between the atoms, and the way the atoms are packed together. This is known as the atomic scale structure. Most ceramics are made up of two or more elements. This is called a compound. For example, alumina (AlO), is a compound made up of aluminium atoms and oxygen atoms. The atoms in ceramic materials are held together by a chemical bond.

The honeycomb form usually is an extruded ceramic applied homogeneously throughout the ceramic carrier or coated on the substrate. Like the various types of catalysts, their configuration also has advantages and disadvantages. Plate-type catalysts have lower pressure drops and are less susceptible to plugging and fouling than the honeycomb types, but plate configurations are much larger and more expensive. Honeycomb configurations are smaller than plate types, but have higher pressure drops and plug much more easily.

These two types of wire gauze that are made of metal have the same ability to transmit the heat efficiently, but the gauze with a ceramic center will allow the heat to be dispersed more evenly. The ceramic at the centre of the wire gauze is enmeshed at high pressure to prevent it from peeling.

very high capacitance per unit volume compared with film- or ceramic capacitors. The permittivity of tantalum pentoxide is approximately three times higher than aluminium oxide, producing significantly smaller components. However, permittivity determines only the dimensions. Electrical parameters, especially conductivity, are established by the electrolyte's material and composition. Three general types of electrolytes are used: Internal losses of electrolytic capacitors, prevailing used for decoupling and buffering applications, are determined by the kind of electrolyte. The large capacitance per unit volume of electrolytic capacitors make them valuable in relatively high-current and low-frequency electrical circuits, e.g. in power supply filters for decoupling unwanted

to build multilayer capacitors with this material, only leaded single layer types are offered in the market. Ceramic capacitors are composed of a mixture of finely ground granules of paraelectric or ferroelectric materials, appropriately mixed with other materials to achieve the desired characteristics. From these powder mixtures, the ceramic is sintered at high temperatures. The ceramic forms the dielectric and serves as a carrier for the metallic electrodes. The minimum thickness of the dielectric layer, which today (2013) for low voltage capacitors is in the size range of 0.5 micrometers is limited downwards by the grain size of the ceramic

However, when dry, clay becomes firm and when fired in a kiln, permanent physical and chemical changes occur. These changes convert the clay into a ceramic material. Because of these properties, clay is used for making pottery, both utilitarian and decorative, and construction products, such as bricks, wall and floor tiles. Different types of clay, when used with different minerals and firing conditions, are used to produce earthenware, stoneware, and porcelain.

Other attempts to extend ceramic petrography include the use of automated image analysis, the palaeontological analysis of microscopic fossils within ceramic thin sections and the combined statistical classification of petrographic and chemical data from artefacts. Thin section archaeological petrography can be applied to a range of other artefact types in addition to ceramics; these include plaster, mortar, mudbricks and lithic implements.

Without any special design features, NP0/C0G class 1 ceramic MLCC chips reach a typical bending strength of 2mm while larger types of X7R, Y5V class 2 ceramic chips achieved only a bending strength of approximately 1mm. Smaller chips, such as the size of 0402, reached in all types of ceramics larger bending strength values.

They are commonly used in the construction of many ceramic articles, where their primary role, apart from their white colour, is to either to impart plasticity or to aid rheological stability during the shaping processes. The name "ball clay" is believed to derive from the time when the clay was mined by hand. It was cut into 15 to 17-kilogram cubes and during transport the corners of the cubes became rounded off leaving "balls". The ceramic use of ball clays in Britain dates back to at

lower capacitance values can fit better the higher frequencies. Aluminum electrolytic capacitors have relatively good decoupling properties in the lower frequency range up to about 1 MHz due to their large capacitance values. This is the reason for using electrolytic capacitors in standard or switched-mode power supplies behind the rectifier for smoothing application. Ceramic and film capacitors are already out of their smaller capacitance values suitable for higher frequencies up to several 100 MHz. They also have significantly lower parasitic inductance, making them suitable for higher frequency applications, due to their construction with end-surface contacting of the electrodes. To increase

with hereditary symbols transmitted up to the fourth generation. In the absence of historical records written by the Dacians (and Thracians) themselves, analysis of their origins depends largely on the remains of material culture. On the whole, the Bronze Age witnessed the evolution of the ethnic groups which emerged during the Eneolithic period, and eventually the syncretism of both autochthonous and Indo-European elements from the steppes and the Pontic regions. Various groups of Thracians had not separated out by 1200 BC, but there are strong similarities between the ceramic types found at Troy and the ceramic types from the Carpathian

The discovery of mud dauber nests with some of the skeletons supports the interpretation that these were secondary burials. Mud daubers do not build their nests underground showing that the remains were left above ground while they decomposed and were then buried. There are two main types of ceramics associated with this site, Potomac Creek Cord-impressed and Potomac Creek Sand-tempered. A smoothed variety of the Cord-impressed is named Potomac Creek Plain.

to changes in humidity both high and low. In high humidity salts become soluble and in low humidity they crystallize. The changing from soluble to crystallization and back damages the surface of the ceramic because salt crystals are larger than liquid salt and therefore will shrink and expand the ceramic body. A white haze on the surface is the first indication of soluble salts, which is the salt crystallizing. Over time, the physical component of the body will crumble until it is completely destroyed.

Two deposits of Middle Preclassic ceramic fragments were excavated in the southwest portion of the plaza. Each deposit consisted of thousands of fragments that had been placed in hollows carved in the limestone bedrock below the plaza. These are the earliest traces of human activity that have been found in the plaza and they have been dated to around 650 BC. These early ceramic deposits were not associated with any kind of construction activity. The earliest traces of

Capable of replacing 2 or more conventional devices, the X2Y ceramic capacitors are ideal for high frequency filtering or noise suppression of supply voltages in digital circuits, and can prove invaluable in meeting stringent EMC demands in dc motors, in automotive, audio, sensor and other applications. The X2Y footprint results in lower mounted inductance. This is particularly of interest for use in high-speed digital circuits with clock rates of several 100 MHz and upwards.

Their chemical composition and structure varies considerably depending on the composition of coal that generated them. The ceramic particles in fly ash have three types of structures. The first type of particles are solid and are called precipitator. The second type of particles are hollow and are called cenospheres. The third type of particles are called plerospheres, which are hollow particles of large diameter filled with smaller size precipitator and cenospheres.

Wet tantalums are not commonly referred to as just 'electrolytics' because usually 'electrolytic' refers to aluminium electrolytics. Ceramic (for values <0.47 micro-farad-µF) and electrolytic (for 0.47 µF and up) are normally the preferred types where their performance is sufficient, since these are the lowest cost types of capacitors. Hence they are very popular in filters of many types.

In Peru, stoves are constructed from "two or three muds and clay based walls surrounding a fire pit". Whereas in Nepal, stoves are constructed from "rice husks and clay". Even though clean cookstoves may help decrease indoor air pollution, traditional methods of cooking often continue to be used because of cultural tradition, the rate of cooking and as well as the preservation of unique flavors.

Purlin In architecture, structural engineering or building, a purlin (or historically purline, purloyne, purling, perling) is any longitudinal, horizontal, structural member in a roof except a type of framing with what is called a crown plate. In traditional timber framing there are three basic types of purlin: purlin plate, principal purlin and common purlin. A "purlin plate" in wooden construction is also called an "arcade plate" in European English, "under purlin", and "principal purlin". The term plate means a major, horizontal, supporting timber. Purlin plates are beams which support the mid-span of rafters and are supported by posts. By supporting

pumps use different types of gear reduction mechanisms to slow the motor rotation when driving the piston. These linkages result in significant energy losses in addition to the inefficiencies of the motor. Inductive pumps use various proprietary coatings to reduce friction drag and increase efficiency. Specific models of inductive pumps incorporate a seal-less ceramic interface with matching ceramic bore and piston interfaces ground to close tolerances that do not require use of elastic seals. Ceramic interfaces are inert to extremely caustic industrial acids, alkalis, and solvents. Inductive pump An Inductive pump is a magnetically regulated positive displacement pump used to

Tunnel construction Tunnels are dug in types of materials varying from soft clay to hard rock. The method of tunnel construction depends on such factors as the ground conditions, the ground water conditions, the length and diameter of the tunnel drive, the depth of the tunnel, the logistics of supporting the tunnel excavation, the final use and shape of the tunnel and appropriate risk management. There are three basic types of tunnel construction in common use: In 2017 experiences show that city subway underground tunnels cost approximately 500 Mio EUR per kilometer.

When the clay is fired up, it should turn to a light pink to white colour, and, to reduce the likelihood of cracking, it should shrink less than 8% after being fired. Clay which meets all the above standards is generally referred to as a "fireclay". To produce the Kenya Ceramic Jiko, two types of skilled labour are needed, a metalworker, and a clay worker.

Forward hydrocyclones remove particles that are denser than the surrounding fluid, while reverse hydrocyclones remove particles that are less dense than the surrounding fluid. In a reverse hydrocyclone the overflow is at the apex and the underflow at the base. There are also parallel-flow hydrocyclones where both the "accept" and "reject" are removed at the apex. Parallel-flow hydrocyclones remove particles that are lighter than the surrounding fluid. Hydrocyclones can be made of metal (mostly steel), ceramic or plastic (such as polyurethane, polypropylene, or other types). Metal or ceramic hydrocyclones are

Construction of these structures consisted of river cobbles aligned in circular patterns of various sizes, typically with adjoining rectangular patios. The smallest structures measured 10m in diameter and the largest were up to 30m in diameter. Additional architectural features including paths, causeways, plazas, and stairways were also recorded throughout the site. It is unclear what function that these structures served within the broader context of the site as a whole. The majority of ceramic artifacts found in these area were shattered and found on the exterior of these structures. Ceramic sherds were rarely found on the interior. This suggests that

Processing of collected sherds can be consistent with two main types of analysis: technical and traditional. Traditional analysis involves sorting ceramic artifacts, sherds and larger fragments into specific types based on style, composition, manufacturing and morphology. By creating these typologies it is possible to distinguish between different cultural styles, the purpose of the ceramic and technological state of the people among other conclusions. In addition, by looking at stylistic changes of ceramics over time is it possible to separate

range for all others. Most discrete capacitor types have more or less capacitance changes with increasing frequencies. The dielectric strength of class 2 ceramic and plastic film diminishes with rising frequency. Therefore, their capacitance value decreases with increasing frequency. This phenomenon for ceramic class 2 and plastic film dielectrics is related to dielectric relaxation in which the time constant of the electrical dipoles is the reason for the frequency dependence of permittivity. The graphs below show typical frequency behavior of the capacitance for ceramic and film capacitors. For electrolytic capacitors with non-solid electrolyte, mechanical motion of the ions occurs.

For capacitors, the volumetric efficiency is measured with the "CV product", calculated by multiplying the capacitance (C) by the maximum voltage rating (V), divided by the volume. From 1970 to 2005, volumetric efficiencies have improved dramatically. These individual capacitors can perform their application independent of their affiliation to an above shown capacitor type, so that an overlapping range of applications between the different capacitor types exists.

Based on fusion temperature, (melting point) refractory materials are classified into three types. All refractories require anchorage systems such as wire formed anchors, formed metal (for example, hexmetal) or ceramic tiles to support the refractory linings. The anchorage used for refractories on roofs and vertical walls are more critical as they must remain able to support the weight of refractories even at the elevated temperatures and operating conditions. The commonly used anchorages have circular or rectangular cross-sections.

For military types the class 2 dielectrics specify temperature characteristic (TC) but not temperature-voltage characteristic (TVC). Similar to X7R, military type BX cannot vary more than 15% over temperature, and in addition, must remain within +15%/-25 % at maximum rated voltage. Type BR has a TVC limit of +15%/-40%.

During operation, the temperature of this ceramic tube can exceed 1200 kelvins. The ceramic tube is filled with mercury, argon and metal-halide salts (for example, sodium iodide). Because of the high wall temperature, the metal halide salts are partly vaporized. Inside the hot plasma, these salts are dissociated into metallic atoms and iodine. The metallic atoms are the main source of light in these lamps, creating a bluish light that is close to daylight with a

there is always some limited slip action. There are several types of balls used in this type of differential. Some of the most common ball materials used by high end racers are ceramic and tungsten based. The advantage to something like ceramic based balls are that they are much harder, and have a longer life expectancy. Often times when using less hard materials, the balls will "flat spot" causing a semi locked direction of the ball. This causes the differential to not turn with a smooth feeling and leaves it with an overall "gritty" feeling. Ball differential A ball differential
