摘要：
Disclosed is a method of manufacturing an oxide superconductor containing at least an alkaline earth metal and copper. This method comprises the steps of heating a material substance containing elements constituting the oxide superconductor, in an atmosphere having an oxygen partial pressure of at most 50 Torr at a temperature ranging from 500°C to 1000°C, and then heating the material substance in an oxygen-containing atmosphere. Also disclosed herein is a method of manufacturing composite oxide powder which is the precursor of the oxide superconductor. This method comprises the steps of heating the material substance in an atmosphere having an oxygen partial pressure of at most 50 Torr at a temperature ranging from 500°C to 1000°C, and crushing the material substance into powder.
