摘要：

Horizontal Bridgman growth on MgO single crystal bars as supports was performed in air with DyBa2Cu3Oy (1-2-3) stoichiometric sample, prepared by hot forging. The Dy2BaCuO5 (2-1-1) size distribution along the growth direction was measured from back scattered electron micrographs using automated image analysis. It was found to be non-uniform and it is concluded that particles coarsen during time spent in the liquid and are pushed by the solid-liquid growth front during the process.
