含镝氯化物熔盐体系热力学及其熔体结构研究

With CALPHAD technology, the thermodynamic properties and phase diagrams of dysprosium chloride and alkali chloride binary systems were systematically assessed and optimized in thermodynamic self-consistency using chemSage integrated thermochemistry software. By X-ray diffraction method and DTA method the intermediate compound and phase diagrams were identified and determined. To describe the thermodynamic properties of solution of complicated molten salts, an appropriate thermodynamic model in the view of the physical properties was to be developed. Therefore, the native relations between thermodynamic properties and structure of melts were elucidated or revealed.For the application of rare earths, one integrated databank of rare earths including thermodynamics, structures, phase diagrams and physical properties, Rare Earths Compound Physical Property Databank (RECPD), is being constructed
