PROCESS OF PRODUCTION OF HIGH-TEMPERATURE-SUPERCONDUCTIVE CERAMICS WITH METAL ADDITIONS Russian patent published in 1994 - IPC

FIELD: production of ceramics. SUBSTANCE: solutions of salts of metals of inorganic acids, for instance caustic silver, in the form of aqueous, aqueous-alcoholic or phenol-alcohol solutions are injected into prepared powders of materials for production of high-temperature superconductive ceramics to form pasty mass out of them. Mass is heated to remove solvent, cooled to room temperature and pressed under pressures which do not disturb structural integrity of starting grains in powders. Then pressed materials are heated till salts of metals of inorganic acids disintegrate. After this sintering of powders is conducted. EFFECT: improved efficiency of process and quality of ceramics.
