Abstract

PURPOSE:To obtain a superconducting material turning into superconductive state at >=77 deg.K, by compression molding a powdery mixture composed of three specific kinds of element components and baking the molded material in an oxidative atmosphere. CONSTITUTION:The objective superconducting material is produced by (1) forming a mixture of a powder composed mainly of Y and belonging to (A1) the 1st component composed of Y and one or more elements selected from Sc, La, Nd, Sm, Eu, Gd, Dy, Ho, Er, Tm, Yb and Lu, a powder composed mainly of elements belonging to (A2) the 2nd component composed of Ba element and a powder composed mainly of elements belonging to (A3) the 3rd component composed of one or more elements selected from Cu, Zn, Ni, Co, Fe, Pd, Ag and Cd and (2) baking the molded article in an oxidative atmosphere at 950-1,200 deg.C in such a manner as to form a sintered material having K2NiF4 structure including monoclinic crystal and composed of the components A1, A2 and A3 of formulas and oxygen component.
