Abstract

The effects of CeO₂ adding on the reduction of Y-211 particle size and the oxygenation temperature on T_c have been studied. It is shown that the decrease of pre-sintering temperature is more effective than adding CeO₂ for the Y-211 particle size reduction. For bulk YBCO, the oxygenation temperature affects not only the critical temperature T_c and other superconducting property, but also its microstructure. Our results show the low oxygenation temperature is suitable for the oxygenation process of melt-textured bulk YBCO. If the oxygenation temperature is above 600 °C, the macrocrack will propagate.
