Theoretical Analysis of the Li, Ca, Ba∥F, WO4 System: Thermal Analysis of the Quaternary System LiF–BaF2–CaF2–BaWO4

详细

The differentiation of the quaternary reciprocal system Li, Ca, Ba∥F, WO₄ was performed based on graph theory using special software. Stable and metastable secant 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–BaF₂–CaF₂–BaWO₄, which is a stable complex of the quaternary reciprocal system Li, Ca, Ba∥F, WO₄, was studied and the coordinates of invariant points were determined.
