Abstract
The interaction of oxygen and cerium-free ions in molten 3LiCl-2KCl eutectic in the temperature range of (723–823) K was studied by the method of potentiometric titration using YZME electrodes. Stable states of cerium compounds in the Ce–O system and the mechanism of interaction of Ce3+ with O2− ions have been established. The solubility constants of cerium oxychloride and oxide compounds at different temperatures were determined. Principal thermodynamic data of CeOCl and Ce2O3 were calculated. The Pourbaix (potential-pO2−) diagram was drawn and summarizes the properties of stable cerium species in the melt.
