Abstract
Mix phase ceramics of Y0.4Ba0.6CuO3-y is examined by an X-ray diffraction and an EPMA methods. When the sintering temperature is high (1050°C), ceramics show a mix phase consisting of CuO, Y2BaCuO6-y and YBa2Cu3O8-y . By lowering the sintering temperature, single phase is obtained. This single phase ceramics show a sharp superconducting transition at 93 K.Keywords
