Abstract

The morphology and the formation of Y₂BaCuO₅ phase in powder melting processed YBa₂Cu₃O₇-x superconductors were investigated. The experimental results show the heat treatment can not change the shape of Y₂BaCuO₅ particles in powder melting processed samples. The formation of round Y ₂BaCuO₅ phase is due to relative content of each constitution of precursor powders in powder melting process. For powder melting process, the excessive liquid phase is eliminated, which restrains the preferred growth of Y₂BaCuO₅ particles.
