Abstract: Phase diagram of the system NaF-Na₂SO₄ was investigated by using the method of registration of cooling curves. The system contains no solid solns. NaF.Na₂SO₄ (Na₃FSO₄) melts congruently at 1060 K. This compd. forms with NaF and also with Na₂SO₄ simple eutectic systems. The thermal dissocn. of Na₃FSO₄ influences the course of liquidus curves of both pure components, NaF and Na₂SO₄. The degree of thermal dissocn. of the compd. was estd. by using the method of liquidus of the second component.
