摘要:
A method of manufacturing an oxide superconductive material, which permits improvement of superconductivity, and simple and easy manufacture of an oxide superconductive material. The method comprises the steps of using pure copper powder and gaseous oxygen, mixing pure copper powder and powder of pure metals or compounds of other component elements, introducing external heat input to part of the powder mixture of raw materials, causing synthetic reaction by the heat of formation generated from combustion reaction between pure copper powder and gaseous oxygen, and causing propagation of the synthetic reaction throughout the entire powder mixture of raw materials by self-propagating high-temperature synthesis.
