Abstract: The quasi-binary system Na₃AlF₆-K₃AlF₆ was optimized based on CALPHAD technique using a computerized optimization procedure called PARROT included in Thermo-calculation. The two-sublattice model was used for the liquid phase in which K¹⁺, Na¹⁺ were taken as cation, and AlF as anion. The compound 2K₃AlF₆·Na₃AlF₆ was modeled as stoichiometric phase. The phase diagram was analyzed according to the assessed result.
