Phase equilibrium in lanthanide halide systems: Assessment of CeBr3 and MBr-CeBr3 systems (M = Li, Na, K, Rb, Cs)

Résumé

This paper performed thermodynamic calculations on the CeBr3 compound and the MBr-CeBr3 binary system over the entire temperature and composition range. The Gibbs energy of CeBr3 was evaluated using an independent polynomial to fit the experimental heat capacity, a two sub-lattice ionic solution model (M+)(P): (Br-, CeBr6-3, CeBr3)(Q) was adopted to describe the liquid phase and the thermodynamic parameters for each phase in the MBr-CeBr3 system were reassessed by using available experimental information on phase diagram and thermodynamic properties. Comparisons between the calculated phase diagram and thermodynamic quantities showed that all reliable experimental information was satisfactorily accounted for by the present thermodynamic description.
