Abstract

Phase composition and compatibilities at 930° to 950°C were determined for the system Eu2O3-BaO-CuO in air. The binary compound Eu2CuO4 dissolves Ba to the extent 0 ≤ x ≤ 0.02 in Eu2-xBaxCuO4, whereas the other binary compounds, Eu2BaO4 and BaCuO2, do not exhibit solid solubility. Three ternary compounds were obtained, Eu2BaCuO5 and two solid solution phases. The first contains the 90 K '123' superconductor and has solubility limits represented by Eu1+xBa2-xCu3O7±y, where 0 ≤ x ≤ 0.5. The second has a solubility limit represented as Eu1+xBa8-xCu4Oy, where 0 ≤ x ≤ 0.44. The limited solid solution range of this phase provides insight concerning the probable solid solution range of the analogous phase in the Y2O3-BaO-CuO system.
