Abstract
The differentiation of the quaternary reciprocal system Li, K, Ca, Ba||F, WO4 was performed based on the graph theory using special software. Stable and metastable complexes of the system were found using a matrix of reciprocal pairs of salts. For the first time, by a set of physicochemical analysis methods (differential thermal, visual polythermal, and X-ray powder diffraction analyses), based on the method of thermal analysis of successive projections of the composition polytope, the quaternary system LiF–K2WO4–CaF2–BaF2–BaWO4, which is a stable complex of the quaternary reciprocal system Li, K, Ca, Ba||F, WO4, was studied and the coordinates of invariant points were determined.
