Calculation of phase equilibria of ternary additive molten salt systems with a common anion
Abstract
Phase diagrams for ternary additive systems LiF + NaF + KF, LiF + NaF + CaF2, LiF + NaF + SrF2 and NaF + KF + SrF2 have been calculated a priori using a set of readily available physical parameters for each component. The method of calculation is based on a simple ion-interaction model developed for binary molten salt systems and now extended to ternary additive salt mixtures. Calculated and experimentally derived phase diagrams are compared and discussed.
