Abstract

The effects of BaZrO₃ addition on the thermal behavior and microstructure of YBCO superconductors have been investigated. The differential thermal analysis indicates that the peritectic decomposition temperature of YBCO precursor powder is not change when BaZrO₃ is doped. The solidification temperature of YBCO changes with increasing of BaZrO₃ addition, thus the window of solidification temperature is affected. The results of scanning electron microscopy show that the BaZrO₃ particles are accumulated along the growth boundary, which result in the constitutional segregation of YBCO. The pushing-trapping theory is used to explain the phenomenon of segregation in the YBCO matrix.
