N2 - The phase diagram for the CuO‐rich part of the La2O3─CuO join was redetermined. La2Cu2O5 was found to have a lower limit of stability at 1002°± 5°C and an incongruent melting temperature of ∼1035°C. LagCu7O19 had both a lower (1012°± 5°C) and an upper (1027°± 5°C) limit of stability. Subsolidus phase relations were studied in the La2O3─CuO─CaO system at 1000°, 1020°, and 1050°C in air. Two ternary phases, La1.9Ca1.1Cu2O5.9 and LaCa2Cu3O8.6, were stable at these temperatures, with three binary phases, Ca2CuO3, CaCu2O3, and La2CuO4. La2Cu2O5 and La8Cu7O19 were stable only at 1020°C, and did not support solid‐solution formation.
