Abstract

The phase relations involving the 24 K n-type Nd2-xCexCuO4 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)CeO2-yNdO1.5 solid solution exists out to y = 0.4. Phase diagrams for NdO1.5-CeO2-CuO (1000°C) and NdO1.5-CeO2 (900° to 1500°C) are presented.
