Thermochemical Transformations in the Twelve-Salt Six-Component Reciprocal System Na,K,Ca,Ba∥F,SO4,WO4

Thermochemical characterization of the twelve-salt system Na,K,Ca,Ba∥F,SO4,WO4 (a 4∥3 system) and the four nine-salt five-component reciprocal subsystems is presented. A comparison of thermochemical relationships is carried out for these nine-salt systems, and the internal structural thermochemical transformations of exchange-reaction stages between all these systems are considered. The effect of a reaction stage on the final product yield is considered for sample chemical reactions. The thermochemical structure of basal tetrahedra of the singular star in the twelve-salt system is studied, and relationships are derived between various models of the system (salt-node indices in the matrix, reaction stages, geometrical figures) and chemical processes that occur in the system. These relationships can be used in experimental design.
