Thermodynamic assessment of NdBr 3 unary and LiBr–NdBr 3 binary system

Abstract

Phase diagram and thermodynamic properties calculations were carried out on the NdBr 3 unary and the LiBr–NdBr 3 binary systems over the entire temperature and composition range, respectively. The Gibbs energy of NdBr 3 was evaluated using an independent polynomial to fit the experimental thermodynamic properties. The liquid phase in the LiBr–NdBr 3 system was described by the two sub-lattice ionic solution model (Li +) P : (Br −, NdBr 6 −3, NdBr 3) 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.
