Cutting triangle NaF–KF–CsCl of the quaternary reciprocal system Na,K,Cs‖F,Cl

Resumo

The quaternary reciprocal system Na,K,Cs‖F,Cl was partitioned into simplexes using graph theory by constructing an adjacency matrix and solving a logical expression. A tree of phases of the system was built, which has a linear structure and consists of three stable tetrahedra divided by two cutting triangles. The cutting triangle NaF–KF–CsCl was experimentally studied by differential thermal analysis. The composition and melting point of the eutectic alloy in the stable triangle were determined.
