Containerless synthesis of ceramic materials using microwave heating
It was demonstrated that microwave heating technique may be employed for the synthesis of a number of multicomponent ceramic oxide-based materials, e.g., YBa2Cu3O7 and CuFe2O4. A characteristic, and potentially extremely useful, feature of such synthesis is that they occur in significantly less time than that required using conventional furnace-based techniques. However, the information obtained to date is necessarily rather empirical, and systematic investigations of the use of microwave heating for the synthesis of ceramic materials are required. The synthesis of ceramic materials at high temperatures are often affected by unwanted, deleterious reactions of the reactants and/or products with the reaction container. Consequently, it is of interest to investigate the high temperature synthesis of ceramic materials using microwave heating in a containerless environment.
