Abstract
By using the CALPHAD technique, an optimization of the binary CeCl 3–AECl 2 (AE=Mg,Ca,Sr,Ba) systems has been carried out. For describing the Gibbs energies of liquid phase in these systems, the new modified quasichemical model in the pair-approximation for short-range ordering was used. From the measured phase equilibria data and experimental thermochemical properties, the CeCl 3–AECl 2 phase diagrams were optimized and calculated. A set of thermodynamic functions has been optimized based on an interactive computer-assisted analysis. The calculated phase diagrams and thermodynamic data are self-consistent.
