Abstract
In the synthesis of the superconducting compound Ba2YCu3O7‐x from a stoichiometric mixture containing BaCO3, Y2O3, and CuO In air, a low‐melting liquid phase is formed at about 890°C. The liquid phase was identified as a ternary eutectic located within the compatibility triangle Ba2YCu3O7‐x–BaCuO2–CuO. The implication of this finding for the processing of Ba2YCu3O7‐x is discussed.Keywords
