Abstract

The effects of CeO2 adding on the reduction of Y-211 particle size and the oxygenation temperature on Tc 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 Tc 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.
