Abstract

Phase equilibria and thermodynamic properties of the KCl-K₂CO₃-NaCl-Na₂CO₃ system were analyzed on the basis of the thermodynamic evaluation of the KCl-NaCl,KCl-K₂CO₃,NaCl-Na₂CO₃,K₂CO₃-Na₂CO₃ and KCl-K₂CO₃-NaCl-Na₂CO₃ systems. The Gibbs energies of individual phases was approximated by two-sublattice models for ionic liquids and crystals. Most of the experimental information was well described by the present set of thermodynamic parameters. The lowest monovariant eutectic temperature in the KCl-NaCl-Na₂CO₃ system is located at 573 ^{{ring operator}}C, with a composition of X_Na2CO3=0.31,X_KCl=0.35 and X_NaCl=0.34.
