Abstract
An oxide superconducting material includes a REBa.sub.2 Cu.sub.3 O.sub.7-x phase (RE designating one or a combination of two or more rare earth elements including Y), particles composed of Ce, Ba, Cu and O dispersed therein, and RE.sub.2 BaCuO.sub.5 or RE.sub.4 Ba.sub.2 Cu.sub.2 O.sub.10 dispersed therein. A method is provided for producing the superconducting material from a mixed powder obtained by adding a Ce--Ba--Cu--O system additive to a starting material powder containing RE, Ba, Cu and O.
