摘要：

Minute amounts of CeO2 additions have a strong effect on the solidification path, physico-chemical parameters and final size distribution of Y2BaCuO5 (211) precipitates of directionally solidified YBa2Cu3O7 (123). Inductive and transport critical currents density (J(c)) measurements indicate a clear increase with CeO2 addition.
