N2 - The subsolidus phase equilibrium in the Y2O3-BaO-CuO system at 900°C in air was determined by solid-state reaction techniques and the powder x-ray diffraction method. The system was found to contain three quaternary compounds, i. e. YBa^CuaOx, YsBaCuOe, and a perovskite like solid solution having a composition of YsxBaa-xCuO^ whose x ranges from 0.07 to 0.25. The structural symmetry of the last material changes from tetragonal orthorhombic tetragonal as x increases. Furthermore, a new ternary compound Ba2CuOx has been isolated whose structure is tetragonal K2NiF4 type with lattice parameters a=3.988A and c=12.988A.
