Abstract

The phase equilibria in the ternary system CeO2–La2O3–Nd2O were systematically studied at a temperature of 1500°C, covering the entire concentration range. No new phases were identified within the specified system. An isothermal section of the phase diagram for the CeO2–LaO2–Nd2O3 ternary system was constructed. The investigation revealed the formation of solid solutions, including cubic solid solutions with a fluorite-type structure F-CeO2, as well as solid solutions based on the hexagonal (A) and cubic (C) modifications of Ln2O3. The phase fields and crystal lattice periods of the formed phases were determined for all investigated systems.
