Abstract

The evolution of thermodynamic models of molten salts and slags, starting with Temkin in 1948, has culminated in today's sub-lattice models. These modern models have permitted the development of large thermodynamic databases of model parameters, which can be used to calculate and predict accurately the properties of multicomponent solutions. The model parameters are mainly obtained by the critical evaluation and optimisation of available thermodynamic and phase equilibrium data for binary and ternary subsystems. The models are then used to estimate the properties of multicomponent slags and salts from these assessed binary and ternary parameters. When used in conjunction with thermodynamic databases for solids and solid solutions (salts, oxides, sulphides, metals, etc.), other liquid solutions (such as liquid metals), and gases, these databases permit the calculation of complex multiphase equilibria in multicomponent systems, with applications in a wide variety of industries. These calculations can be performed with general commercial software for Gibbs energy minimisation, which can also be incorporated into process simulation software packages.
