| Abstract: | High T superconducting single phase polycrystalline compounds with nominal components of 4BaO:6CuO:Y2O3 and 4EaO:3CuO:Y2O3 were prepared by solid-state reaction method. Their superconducting transition middle temperature, Zero-R temperature, superconducting transition width, and diamagnetic transition onset temperature are 93.6k, 92.0k, 1.2k and 92.9k respectively. The formation problems of ceramic phase in the different sintering conditions are investigated using X-ray diffraction. |
