Abstract

PURPOSE:To obtain a superconductor which attains superconductive state at >=77K by compression-molding a powder mixture consisting of specified three element components, and calcining the molded product in oxidizing atmosphere. 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 contains at least one kind of element selected from Cu, Zn, Ni, Co, Fe, Pd, Ag and Cd. Powder consisting primarily of element(s) belonging to the group A1, is mixed with powder consisting primarily of element(s) belonging to the group A2 and powder consisting primarily of element(s) belonging to the group A3. The powder mixture is compression-molded and calcined at 950-1,200 deg.C in oxidizing atmosphere to form thus a sintered body having K2NiF4 structure contg. rhombic crystals. The sintered body provides an aimed superconductor consisting of A1, A2, A3 and O, wherein each A1, A2 and A3 is contained in the proportion defined by inequalities.
