| 简介 | An oxide superconducting material includes a REBa2Cu3O7-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 RE2BaCuO5 or RE4Ba2Cu2O10 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. | ||
