A methodology for determining hidden partitioning elements while differentiating complexing multicomponent systems was developed using exchange reactions in ternary mutual systems and tested on ten quaternary mutual systems. For the first time, using a combination of such physicochemical analysis methods as differential thermal, X-ray powder diffraction, and projection-thermographic analyses, the LiF-K2WO4-CaF2-BaF2 quaternary system was studied, which involves the hidden partitioning element K2WO4-LiBaF3 and is a stable partitioning complex of the Li,K,Ca,Ba∥F,WO4 quinary mutual system. The coordinates of nonvariant points of the quaternary system were found.

The developed methodology effectively identifies hidden partitioning elements in complex multicomponent systems, providing valuable insights into physicochemical interactions in the LiF-K2WO4-CaF2-BaF2 system.
