摘要：
A metal oxide-type superconductive material is produced by a process which comprises a first step of subjecting a powder raw material containing given proportions of metal elements to be contained in said metal oxide-type superconductive material, to mechanical grinding and alloying simultaneously to obtain an alloy powder and a second step of heat-treating the alloy powder in an oxygen-containing gas atmosphere to obtain a metal oxide.The superconductive material obtained has a high density, a low porosity, a high strength and a high critical current density.
