|Abstract:||In this work a thermodynamic assessment of the LiF-NaF-CaF2-LaF3 system iis reported. For the thermodynamic modelling of the liquid phase, the classical polynomial model and the modifed 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. Key words: Molten salts, phase diagram, dierential scanning calorimetry,thermodynamics|
