Abstract

In this work a thermodynamic assessment of the (LiF+NaF+CaF2+LaF3) system is reported. For the thermodynamic modeling of the liquid phase, the classical polynomial model, and the modified quasi-chemical model were used in parallel and compared. The extrapolation to higher order systems was done according to the Toop mathematical formalism. Furthermore, differential-scanning calorimetry data of the ternary (LiF+CaF2+LaF3), (NaF+CaF2+LaF3), and the quaternary (LiF+NaF+CaF2+LaF3) mixtures are presented. Good agreement between the experimental data and the thermodynamic assessment was obtained.
