摘要：

Segregation of second-phase particles within Y1Ba2Cu3O7-y domain was investigated in melt-textured Y-Ba-Cu-O with metal oxide (CeO2, SnO2, and ZrO2) addition. It is found that coarse particles (Y2Ba1Cu1O5) are trapped with a special pattern in the interior of Y1Ba2Cu3O7-y domain, while fine BaCeO3 and BaSnO3 particles are present within the remnant liquid-phase region. During the growth of Y1Ba2Cu3O7-y domain, fine particles appear to be pushed out of the advancing Y1Ba2Cu3O7-y/liquid interface toward the liquid phase, The particle segregation that occurred during peritectic growth of the Y1Ba2Cu3O7-y domain was explained in terms of the Uhlmann-Chalmers-Jackson theory based on the particle interaction at solid/liquid interface.
