Thermodynamic description of the AgCl–CoCl2–InCl3–NaCl system

摘要: Abstract Critical thermodynamic evaluations and optimizations of the AgCl–CoCl2, AgCl–InCl3, AgCl–NaCl, InCl3–NaCl CoCl2–InCl3 systems were carried out in present work within framework CALPHAD approach. The molten salt phase was described by Modified Quasi-chemical Model, while Compound Energy Formalism with various lattice ratios used to treat terminal solid solutions. two binary double salts (Na3InCl6 Ag3InCl6) treated as stoichiometric compounds which Gibbs energies modelled following Neumann-Kopp rule. All model parameters optimized terms required equilibria thermochemical data arising from experimental measurements theoretical predictions (First-principles method empirical equation). A set self-consistent database for AgCl–CoCl2–InCl3–NaCl quaternary system finally derived merging relevant phases all (model CoCl2–NaCl adopted literature) based upon Kohler–Toop interpolation technique order facilely calculate properties sub-ternary systems. calculated results involving multicomponent will support beneficial instructions related industrial processes.
