Thermodynamic evaluation and optimization of the (NaCl + KCl + MgCl 2 + CaCl2 + ZnCl2) system

摘要

A complete critical evaluation of all available phase diagram and thermodynamic data has been performed for all condensed phases and relevant gaseous species of the (NaCl + KCl + MgCl2 + CaCl2 + ZnCl2) system, and optimized model parameters have been found. The (NaCl + KCl + MgCl2 + CaCl2) subsystem has been critically evaluated in a previous article. The model parameters obtained for the binary and ternary subsystems can be used to predict thermodynamic properties and phase equilibria for the multicomponent system. The Modified Quasichemical Model for short-range ordering was used for the molten salt phase.
