摘要：

Four-component systems comprising alkali-metal halides and chromates are used as fused electrolytes for chemical current sources, heat-storage materials, media for the synthesis of various compounds, etc. The Li,K||F,Cl,CrO4 reciprocal four-component system has been analyzed. The system has been triangulated to simplexes using theory of graphs. The phase tree of the system has been designed and used to predict the number of compositions of crystallizing phases in the stable elements. The phases crystallizing in the LiF-KCl-K2CrO4 stable triangle were identified by X-ray powder diffraction. Phase equilibria in the LiF-LiCl-Li2CrO4-KCl stable tetrahedron have been studied by differential thermal analysis. The characteristics of the four-component eutectic alloy were determined (equiv. %): LiF, 1.0; LiCl, 29.8; Li2CrO4, 45.5; KCl, 23.7; melting point, 305 degrees C.
