Abstract
PURPOSE:To obtain a superconductor which attains superconductive state at >=77K by precalcining a powder mixture consisting of two components among specified three element components, pulverizing obtd. precalcined product, molding a powder mixture consisting of the pulverized product and residual components, and calcining finally the molded product. CONSTITUTION:A first component (A1) contains at least one kind of element selected from Er, Sc, La, Nd, Sm, Eu, Gd, Dy, Ho, Tm, Yb, and Lu. A second component (A2) contains Sr or/and Ca. A third component (A3) contains at least one kind of element selected from Cu, Zn, Ni, Co, Fe, Pd, Ag, and Cd. A powder mixture consisting of two components among said three components as primary component is prepd. and precalcined at a temp. below a final calcination temp., and obtd. precalcined product is pulverized. Obtd. powder is mixed with powder consisting primarily of residual components, and the mixture is molded. Obtd. molded product is calcined finally at 950-1,200 deg.C in oxidizing atmosphere to form thus a sintered body having K2NiF4 structure contg. rhombic crystals. The sintered body is an aimed superconductor consisting of A1, A2, A3 and O wherein each content of A1, A2 and A3 is defined by the inequalities.
