Study of the cutting triangle NaF–KCl–CsCl of the quaternary reciprocal system Na, K, Cs||F, Cl

详细

The quaternary reciprocal system Na, K, Cs||F, Cl was partitioned into simplexes by a geometric method. A tree of phases of the system was constructed, which has a linear structure and comprises three stable tetrahedra divided by two cutting triangles. The cutting triangle NaF–KCl–CsCl was experimentally studied by differential thermal analysis. The composition and melting point of a eutectic alloy in the stable triangle were determined.
