Thermodynamic assessment of NdBr3 unary and LiBr–NdBr3 binary system

Phase diagram and thermodynamic properties calculations were carried out on the NdBr3 unary and the LiBr–NdBr3 binary systems over the entire temperature and composition range, respectively. The Gibbs energy of NdBr3 was evaluated using an independent polynomial to fit the experimental thermodynamic properties. The liquid phase in the LiBr–NdBr3 system was described by the two sub-lattice ionic solution model (Li+)P: (Br−, NdBr6−3, NdBr3)Q. Comparisons between the calculated phase diagram and thermodynamic quantities show that all reliable experimental information was satisfactorily accounted for by the present thermodynamic description.
