Calculation and optimization of LaBr3–MBr (Li–Cs) phase diagrams by CALPHAD method

Phase diagram of LaBr3–MBr (M=Li–Cs) pseudo-binary systems were reassessed by CALPHAD method with Associate Model and Redlich–Kister Model. In addition the LaBr3–LiBr system was optimized through the application of the Quasichemical Model, and LaBr3–RbBr system was optimized by Partially Ionic Two-sublattice Model. Optimized thermodynamic properties were compared with the data previously calculated by Quasichemical Model and Partially Ionic Two-sublattice Model as well as with experimental data. The influence of the used models for calculated thermodynamic properties has been discussed.
