Phase diagrams and thermodynamic properties of KCl-KF, KCl-AlCl3, KF-AlF3, KCl-KF-AlF3 systems have been analyzed based on the experimental data. The Gibbs energies of the liquid and halite phases were approximated with the two-sublattice model for ionic liquid and crystal, respectively. The Gibbs energies of other phases were approximated by the line compound model. Most of the experimental information could be reproduced by the present set of thermodynamic parameters. This set of parameters can be predicted from the phase equilibria and thermodynamic properties at full range of composition in KCl-KF-AlF3 system.
