The thermodynamic data for the YO1.5–BaO, BaO-CuOx, and YO1.5–CuOx quasi-binary systems were optimized from experimental phase diagrams. They were used to calculate tentative phase diagrams for the YO1.5–BaO—CuOx quasi-ternary system. The equilibrim liquidus surface and the isothermal sections of the ternary system at 900°, 925°, 950°, 975°, and 1000°C were calculated. The isopleths containing YBa2Cu3O7-δ were also calculated.
