Is platinum a metal?
The name platinum is derived from the Spanish “platina”, meaning “little silver”. Platinum is a lustrous silvery-white, malleable, ductile metal and a member of group 10 of the periodic table of the elements. It has the third highest density, behind osmium and iridium.
Why platinum is so expensive?
Platinum is an expensive metal commonly found in jewellery, however, the rare metal rhodium holds more value. Platinum is the second highest valued metal. Platinum is denser, and thus more material weight is needed to produce the same ring than from white gold. Platinum alloys used in jewellery are purer.
Is Platinum good for health?
4. It is hypoallergenic. Platinum is one of the metals that are available in the market that do not cause allergic reactions to those who wear it. Platinum is 90-95 percent pure, so you don’t have to worry about other allergenic alloys such as nickel getting added to it as you do with gold.
What is so special about Platinum?
The white silver metal known as platinum is the heaviest of the precious metals, weighing almost twice as much as karat gold. It is the least reactive metal and it has a very high melting point. These characteristics, along with its chemical stability, make platinum extremely useful in industrial applications.
Is platinum bad for your health?
* Platinum may cause a skin allergy. If allergy develops, very low future exposure can cause itching and a skin rash. * Platinum may cause an asthma-like allergy. Future exposure can cause asthma attacks with shortness of breath, wheezing, cough, and/or chest tightness.
Is platinum worth more than gold?

What is the strongest metal?
What is the strongest thing on earth?
Diamond is the hardest substance found on earth in so many natural forms, and it is an allotrope of carbon. The hardness of diamond is the highest level of Mohs hardness – grade 10. Its microhardness is 10000kg/mm2, which is 1,000 times higher than quartz and 150 times higher than corundum.
What metal is bulletproof?
Created by melting aluminum around hollow metal spheres, composite metal foam is 70% lighter than sheet metal and can absorb 80 times more energy than steel. It is fireproof, radiation-resistant, and even bulletproof.
Is Tungsten harder than diamond?
Tungsten is rated at about a 9 on the Mohs scale of hardness. A diamond, which is the hardest substance on earth, is rated at a 10. Tungsten carbide is about 2 or 3 times harder than titanium and cobalt chrome.
What’s the hardest thing in the world?
If the conditions are just right, carbon atoms can form a solid, ultra-hard structure known as a diamond. Although diamonds commonly known as the hardest material in the world, there are actually six materials that are harder.
What is the hardest substance in the world?
According to the Mohs Hardness Scale, tooth enamel earns a 5. That means it’s about as hard, or harder, than steel. For reference, diamonds are the strongest substance on earth, ranking 10 on the Mohs scale.
What can damage a diamond?
Inherent Flaws. The number one reason a diamond becomes damaged is the presence of an intrinsic flaw (natural inclusion) in the diamond itself. Although natural inclusions are typical (and part of the diamond’s unique fingerprint), the presence of an inclusion makes the diamond vulnerable to chips and cracks.
Can you ruin a diamond?
Diamonds are hard, but they can be damaged. It is possible to break or chip a diamond. Breaking or chipping isn’t the only way to damage a diamond. You can damage a diamond with chemicals that cause it to look dull and cloudy or discolor the stone until it is professionally cleaned.
Is it bad to clean your diamond ring too much?
No, you can’t clean your engagement ring too much when it’s being done the right way. But, if you’re using all kinds of harsh chemicals regularly that’s when you’re doing too much. Those chemicals will end up damaging the metal and stones, affecting the overall look of the ring.
Will bleach hurt my diamond ring?
Don’t use harmful solutions Chlorine bleach or abrasives (such as household cleansers or toothpaste) should never be used when cleaning diamond jewelry. Chemicals like chlorine can damage some of the metals used to alloy gold for diamond settings and abrasives can scratch gold and other metals.
Je, platinamu ni chuma? Jina platinamu linatokana na Kihispania <unk>platina<unk>, linalomaanisha <unk> fedha ndogo<unk>. Platinamu ni chuma cha rangi ya fedha, nyembamba, na cha kawaida, na ni sehemu ya kikundi cha 10 cha meza ya vipengele. Ina wiani wa tatu kwa ukubwa, nyuma ya osmium na iridium. Kwa nini platinamu ni ghali sana? Platinamu ni chuma ghali ambacho hupatikana kwa kawaida katika vito, hata hivyo, chuma cha Rhodium chenye kupendeza kina thamani zaidi. Platinamu ni chuma cha pili chenye thamani zaidi. Platinamu ni nzito zaidi, na kwa hiyo uzito zaidi wa vifaa huhitajiwa kutokeza pete ileile kuliko kutoka dhahabu nyeupe. Aloi za platinamu zinazotumiwa katika vito ni safi zaidi. Je, platinamu ni nzuri kwa afya? 4. Uwe na uhakika Ni hypoallergenic. Platinamu ni moja ya metali ambazo zinapatikana sokoni ambazo hazisababishi athari za mzio kwa wale wanaozivaa. Platinum ni safi kwa asilimia 90-95 na kwa hivyo hauhitaji kuwa na wasiwasi juu ya alloys nyingine za allergenic kama vile nikeli kuongezwa kwa hiyo kama unavyofanya na dhahabu. Ni nini kipekee sana kuhusu Platinamu? "Platinamu, chuma cha fedha, ni chuma chenye uzito mkubwa zaidi, na kina uzito mara mbili zaidi ya dhahabu.""" Ni chuma ambacho hakishiriki sana na kina kiwango cha juu sana cha kuyeyuka. Sifa hizo, pamoja na uthabiti wake wa kemikali, hufanya platinamu iwe yenye manufaa sana katika matumizi ya viwanda. Je, platinamu ni mbaya kwa afya yako? Platinum inaweza kusababisha mzio wa ngozi. Ikiwa mzio unatokea, mfiduo mdogo sana wa wakati ujao waweza kusababisha kukwaruza na mchochota wa ngozi. Platinum inaweza kusababisha mzio kama wa pumu. Kuambukizwa wakati ujao kunaweza kusababisha mashambulizi ya pumu yenye upungufu wa pumzi, kupiga kelele, kikohozi, na/au mfupa wa kifua. Je, platinamu ina thamani zaidi ya dhahabu? Platinum kwa kawaida kuuzwa kwa bei ya juu kuliko dhahabu na pamoja na platinum's nadra ikilinganishwa na dhahabu, 'platinum' kama adjective imekuwa kuhusishwa na ngazi ya juu ya umaarufu kuliko dhahabu. Licha ya matatizo ya platinamu na dhahabu sasa kuuzwa juu yake, sifa hiyo imebaki. Ni chuma gani chenye nguvu zaidi? Ni nini kilicho na nguvu zaidi duniani? Almasi ni dutu ngumu zaidi duniani, na ni allotrope ya kaboni. Nguvu ya almasi ni kiwango cha juu cha ugumu wa Mohs <unk> daraja la 10. Microhardness yake ni 10,000 kg mm2, ambayo ni mara 1,000 ya juu kuliko quartz na mara 150 ya juu kuliko corundum. Ni nini chuma kisichoweza kupigwa na risasi? Kwa kutengeneza alumini iliyoyeyuka kuzunguka mviringo wa chuma, povu ya chuma iliyoundwa ni nyepesi kwa 70% kuliko karatasi ya chuma na inaweza kunyonya nishati mara 80 zaidi ya chuma. Ni sugu kwa moto, sugu kwa mnururisho, na hata sugu kwa risasi. Je, tungsten ni ngumu kuliko almasi? Tungsten ni kiwango cha 9 katika kiwango cha Mohs cha ugumu. Almasi ni kitu kigumu zaidi duniani, na inahesabiwa kuwa na kiwango cha 10. Tungsten carbide ni ngumu zaidi kuliko titani na cobalt. Ni nini jambo gumu zaidi ulimwenguni? Hali zikiwa sawa, atomu za kaboni zaweza kufanyiza muundo imara, mgumu sana unaoitwa almasi. Ingawa almasi ni kitu kigumu zaidi duniani, kuna vitu vingine sita ambavyo ni vigumu zaidi. Ni nini kitu kigumu zaidi ulimwenguni? Kulingana na kiwango cha Mohs, enamel ya meno hupata alama 5. Hiyo inamaanisha ni ngumu kama, au ngumu zaidi, kuliko chuma. Kwa mfano, almasi ni kitu chenye nguvu zaidi duniani, na ni namba kumi katika kiwango cha Mohs. Ni nini kinachoweza kuharibu almasi? Udhaifu wa Asili. Sababu ya kwanza ambayo almasi huharibiwa ni kuwapo kwa kasoro ya asili (kuingizwa kwa asili) katika almasi yenyewe. Ingawa inclusions asili ni ya kawaida (na sehemu ya alama ya kidole ya kipekee ya almasi), uwepo wa inclusion hufanya almasi hatari kwa chips na nyufa. Je, unaweza kuharibu almasi? Almasi ni ngumu, lakini zinaweza kuharibiwa. Inawezekana kuvunja au kupasua almasi. Kuvunjika au kupasuka si njia pekee ya kuharibu almasi. Unaweza kuharibu almasi kwa kutumia kemikali ambazo huifanya ionekane kuwa isiyo na rangi au yenye rangi mbaya hadi iwe imesafishwa na mtaalamu. Je, ni vibaya kusafisha pete yako ya almasi kupita kiasi? Hapana, huwezi kusafisha pete yako ya uchumba sana wakati inafanywa kwa njia sahihi.

Je, bleach itaumiza pete yangu ya almasi? Usitumie suluhisho zenye madhara Chlorine bleach au abrasives (kama vile vifaa vya kusafisha nyumba au toothpaste) haipaswi kamwe kutumiwa wakati wa kusafisha vito vya almasi. Chlorine inaweza kuharibu baadhi ya metali zinazotumiwa kutengeneza dhahabu kwa ajili ya kuunganisha almasi na abrasives inaweza kuharibu dhahabu na metali nyingine.
