Abstract

Rapid solidification of YBa2Cu3O7−x, EuBa2Cu3O7−x and GdBa2Cu3O7−x has resulted in the formation of amorphous materials with crystallization temperatures in the range of 730–750°C. Higher temperature anneals in oxygen result in the evolution of the orthorhombic phase. The peritectic decomposition temperature for MBa2Cu3O7−x→M2BaCuO7 + liquid (M=Y, Eu, Gd) is in the range of 1035–1085°C with the Eu and Gd compositions having the highest values.
