Abstract

The thermodynamic optimization of NaCl-CeCl₃ has been carried out through CALPHAD method, and a set of reliable parameters has been obtained to describe this system. The calculated phase diagram and other thermodynamic properties have a good agreement with experimental data. Based on Butler's equation and thermodynamic database established by CALPHAD method, the model for surface tensions of molten chlorides containing rare earths has been modified and the surface tensions of MCl-CeCl₃(M=Li, Na, K, Cs) have been calculated. The results show that the model parameter β which describes the relationship between the Gibbs energies of bulk and surface phase is closely related to the molten salt systems. The value of β increases with the ionic radius of alkali metal in the molten salt mixtures in question. The relationship between the composition of bulk and surface phase in these mixtures has also been investigated in this work.
