Abstract
PURPOSE:To obtain a superconductor exhibiting superconductivity at the b.p. of liquid N2 by forming a sintered body having K2NiF4 structure contg. rhombic crystals by mixing powders contg. specified three groups of elements in specified proportions and in specified order, and calcining the mixture in oxidizing atmosphere. CONSTITUTION:A first component corresponding to 10-60atom.% (basing on the whole compsn.) consisting of elements selected from Er, Sc, La, Nd, Sm, Eu, Gd, Dy, Ho, Tm, Yb, and Lu, and second component corresponding to 20-50atom.% (basing on the whole compsn.) consisting of a combination of Ba, Sr, or/and Ca, and a third component corresponding to 30-65atom.% (basing on the whole compsn.) consisting of elements selected from Cu, Zn, Ni, Co, Fe, Pd, Ag, and Cd are prepd. A powder mixture consisting of two components among the above described three components is then prepd., and the mixture is precalcined, and the precalcined product is pulverized, then the product is mixed with powder contg. residual components. Obtd. powder mixture is compression-molded, and obtd. molded body is calcined finally at 950-1,200 deg.C in oxidizing atmosphere to form thus a sintered body having K2NiF4 structure contg. rhombic crystals. Thus, an aimed superconductor is obtd.
