Анотация: The aim of this paper is studying the fusibility diagram of a ternary system of sodium, cesium and calcium sulfates. Methods. The studies were conducted by differential thermal analysis (DTA) method; to build a liquidus surface we used visual polythermal analysis (VPA); X-ray diffraction analysis (XRDA) of the starting salts and the resulting compound was carried out on a DRON -2 diffractometer; phase relationships were studied using a synchronous thermal analyzer of a STA 409PC modification (thermal analyzer), manufactured by NETZSCH German company. Results. In the phase diagram, the nature and coordinates of invariant points (NVP) are revealed. The liquidus surface is represented by the crystallization fields of the starting components and binary compounds. Conclusions. Under the action of the third component, solid solutions formed on the double side of Na2SO4 − CaSO4 decompose.
