The LiCl-LiH, the LiH-LiI. the LiCl-LiI, and the LiCl-LiH-LiI systems were critically assessed by means of the CALPHAD technique. The liquid phase was described by the two sublattice model, (Li+)(Cl-,H-,I-). The end-member-based solid solution LiCl, LiH and LiI with the same structure was modeled as the formula Li(Cl,H,I). On the basis of experimental phase diagram information and thermodynamic data, the phase diagram of the LiCl-LiH, the LiH-LiI. the LiCl-LiI system and five vertical sections and one liquidus surface projection in the LiCl-LiH-LiI systems were optimized using Thermo-Calc software, and a set of self-consistent thermodynamic parameters of the LiCl-LiH-LiI system was obtained.
Keywords:Phase diagram; LiCl-LiH-LiI ternary system; CALPHAD technique
