MODELING OF QUASIBINARIES OF Na+, Сa2+ // O2-, F- SYSTEM

Thermodynamic modeling of phase equilibria of the Na+, Ca2 + // O2-, F- system in the frame of the generalized theory of "regular" ionic solutions was carried out. The equations for the activities of the system components were derived. The standard Gibbs energy of the exchange reaction was calculated. The values of the energy parameters of the model were determined and the phase diagrams of the binary systems were constructed.
Key words: thermodynamic modeling, phase diagrams, Na+, Сa2+// O2-, F- system
