Abstract:

A substantially single phase superconducting composition is formed from a of 123 molar ratio of fine powders of a superconducting rare earth oxide, CuO, and BaCo3. The mixed powders and shaped articles formed from the mixed powders are calcined, sintered, and cooled in an oxygen containing atmosphere. The cooling step is done slowly to improve the superconducting properties. The article formed is a substantially single phase superconducting composition.
