Abstract
Phase equilibrium studies of the PbO x CaOCuO system were conducted from the subsolidus at 770°C to the melting of Ca 2CuO 3 at 1034°C. No ternary oxide compounds were found. Twelve isothermal sections and a liquidus diagram outlining the primary phase fields are presented. At 770°C, in the subsolidus, Ca 2PbO 4 was found to be in equilibrium with Ca 2CuO 3, CaO, PbO x and CuO. The eutectic melting temperature is ≈ 780°C, and the eutectic melting reaction is: PbO + Ca 2PbO 4 + CuO → liquid. Two additional ternary melting reactions were characterized. Above 1034°C, the only solid compounds remaining are CaO and CuO.
