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.
