Abstract

The YBCO superconductors with Y₂O₃ addition were prepared by a modified melt textured process and the effects of excess Y ₂O₃ addition on the physical properties of melt textured YBCO have been investigated. It is found that the melt temperature of YBCO samples decreases drastically with the increasing Y₂O₃, and the maximum levitation forces are drastically different for samples with different Y₂O₃ addition. It is also found that the optimal Y₂O₃ addition to YBCO is about 10wt%. Considering the microstructure and the starting composition, the results are well discussed and interpreted.
