Modelling of thermodynamic properties of NdBr3–MBr (M=Li–Cs) pseudobinary systems
Source abstract
Abstract
Abstract The phase diagrams of NdBr 3 –MBr (M=Li…Cs) pseudobinary systems measured by different authors show discrepancies. Therefore in the present work mentioned systems have been re-examined and the compatibility of their phase diagrams have been evaluated. The dependences of mixing enthalpies on NdBr 3 mole fraction, heat capacities of M 3 NdBr 6 intermediate compounds (M=Li…Cs) formed in the investigated systems and evaluated phase diagrams have been used for optimization of coupled phase diagrams. The experimental data have been used to predict of an unknown thermodynamic properties of M 2 NdBr 5 and MNd 2 Br 7 (M=Li…Cs) intermediate compounds. The Associate Model of the liquid phase has been applied and the dependence of mixing entropy on NdBr 3 mole fraction for the set of the phase diagrams have been found. The amount of the main associate {3M + +NdBr 6 3− } in each system has been estimated.
