Thermodynamic Optimization and Calculation of LiBr-SrBr_2 System

Binary LiBr-SrBr2 system was calculated and optimized by CALPHAD (Calculation of Phase Diagram) technique. The calculated eutectic has a composition of 34. 93% (mole fraction) SrBr2 at 709. 20 K. The peritectic temperature of compound LiSr2Br5 is 760. 00 K with 55. 43%(mole fraction) SrBr2. The enthalpy of mixing and entropy of mixing of the liquid melted have been predicted from data for the LiBr-SrBr2 system. The calculations based on the obtained descriptions show good agreement with experimental phase diagrams and thermodynamic values.
