Abstract
A method of manufacturing an oxide superconductor by heating a raw material for an oxide superconductor composed of MBa.sub.2 Cu.sub.3 O.sub.7-.delta., where M represents at least a single element selected from a group of Y, Nd, Sm, Eu, Gd, Dy, Ho, Er, Tm, Yb and Lu, to a temperature higher than a peritectic reaction temperature for melting the same and thereafter reducing the temperature to the peritectic reaction temperature to crystallize the oxide superconductor by peritectic reaction. A method of forming a dispersion solution of powder of a raw material for an oxide superconductor and applying the same on a substrate to prepare a thick film. A method of dipping a single crystal of M.sub.2 BaCuO.sub.5 in a molten solution of a mixture of BaCuO.sub.2 and CuO to form a thin film of an oxide superconductor on the single crystal. A method of manufacturing a bulky oxide superconductor by dipping a porous sintered material of M.sub.2 BaCuO.sub.5 in a molten solution of a mixture of BaCuO.sub.2 and CuO.
