CERAMIC MATERIAL PRODUCTION METHOD Russian patent published in 1995 - IPC

FIELD: superconductors production. SUBSTANCE: complex product of oxidation reaction of two or more metals in oxidized state is produced by location of suited initial material beside permeable mass of metal-bearing compound in oxidizing atmosphere with following load heating to obtain mass of melted initial material. Melted metal penetrates permeable mass and interacts with it and oxidizing atmosphere creating complex product of oxidation reaction, in particular, high-temperature superconductor. Methods to preserve form of produced pieces are described. The method are useful for production of superconducting perovskites. As initial metal they use copper and / or cuprous oxide or aluminum, as oxidizing atmosphere oxygen as metal-bearing compound at least one oxyl of rare Earths and at least one oxide of alkaline-Earths, for example, yttrium and /or lanthanum and barium. Source of initial metal may have additionally noble metal, and penetrating filler addition of inert component. Produced material has no less than 90 volume of deformed pervoksite with boiling point of 92 K. EFFECT: new methods of composite materials production. 13 cl, 7 dwg
