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 LiSr2 Brs 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.
