Abstract

The phase relations involving the 24 K n-type Nd_2-xCe_xCuO₄ superconductor were investigated at 1000°C in air. The terminal solid solubility was confirmed to be x = 0.2. This solid solution is the only ternary phase in the Nd₂O₃-CeO₂-CuO diagram. A binary (1 - y)CeO_2-yNdO_1.5 solid solution exists out to y = 0.4. Phase diagrams for NdO_1.5-CeO₂-CuO (1000°C) and NdO_1.5-CeO₂ (900° to 1500°C) are presented.
