    Abstract:

    The morphology of powder melting processed Y2BaCuO5 particles quenched in different heat treatment system was investigated, and compared with that of the Y2BaCuO5 particles in melt texture growth process and melt powder melt growth process. The forming mechanism of equiaxed Y2BaCuO5 particles in powder melting process was revealed. The results show that the composition of precursor powder make the excess liquid phase in powder melting process decrease, which inhibits the preferential growth of Y2BaCuO5 particles.
