Abstract: Experimental data on solid-liquid phase equilibria in the binary systems Na3AIF6-Na3FSO4, Na3AIF6-Na2SO4, Na3FSO4-Na2SO4 and the ternary system Na3AIF6-Na3FSO4-Na2SO4 are presented. A model of molten salt mixtures based on the assumption of the existence of ionic pairs was applied to these systems. The temperatures of primary crystallization of Na3AIF6, Na3FSO4, and Na2SO4 were calculated. A good agreement between the experimental and calculated data was achieved.
