摘要

The YBCO superconductors with Y₂O₃ addition were prepared by a modified melt textured process and the effects of excess Y₂O₃ addition on the levitation force of melt textured YBCO have been investigated. The results indicate that the melt temperature of YBCO samples decreases drastically with the increasing excess Y₂O₃, whereas the solid state reaction temperature increases slightly as the Y₂O₃ addition rises. The maximum levitation forces (MLF) are much different for samples with different Y₂O₃ addition. It is found that the optimum Y₂O₃ excess in YBCO for the (strong MLF) is about 10 wt.%. Combined with the micro structure and the starting composition, the results are discussed in detail.
