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.
