Under these hydro(solvo)thermal conditions, the conventional and unconventional chemical reactions involve the interaction between neutral and ionic species in solution and one or more solid phases. Through chemical, mass, and electroneutrality balances, for all species involved, reaches the equilibrium between solid phases . Thus, a hydro(solvo)thermal synthesis occurs through the interplay of minerals solubility in a solution heated under high pressure. In such manner, that the solvent will be heated to the boiling point temperatures, by an increase in autogenous heating pressures (i.e., the pressure generated during autoclave heating) . This way, it explores how the parameters of experimental synthesis (e.g., temperature, pressure, solvent, nature of the precursors, reaction time, and so on) affect the formation of crystalline particles leading to highly adjustable properties of a given target material . In relation to the materials prepared by this strategy, we highlight the superiority in applications such as superionic conductors , chemical and gas sensors , electronically conductive solids , complex ceramic oxide and fluorides , magnetic materials , optoelectronic devices , and so on. Furthermore, it is known that the kinetics of hydro(solvo)thermal reactions undergo significant changes when associating technologies such as electrochemistry, microwave, sonochemistry, and others . Among these, microwave-assisted hydro(solvo)thermal synthesis is one of the main unconventional methods widely employed to produce advanced materials . Microwave enhanced heating is, of course, based on more efficient dielectric heating of specific solvent, which is responsible to absorb-convert energy into heat . The uniqueness of the dielectric heating mechanism causes the specific (thermal) effects of microwaves not being possible to reach by conventional heating. Undoubtedly, the use of microwaveassisted heating contributes to an increase in crystallization kinetics, in orders of magnitude, thereby improving material productivity and favoring the obtainment of more complex structures . Also, is well established that the use of microwave energy substantially impacts the physicochemical properties of these advanced materials . This feature can also offer many benefits by making it cost-effective, and reducing reaction time and energy in processing when microwaves are used, thus making it an interesting strategy to obtain of novel designed advanced materials with unique physicochemical properties .
