Thermodynamics of Surface Tension of Molten Salt Mixtures

Abstract

The thermodynamic model has been discussed for the surface tension of molten salt mixtures in the common ion alkali-halide, carbonate, sulfate and nitrate systems. In addition, the extension of the above model has been investigated to alkaline-earth halide systems and reciprocal alkali-halide systems. Based on the present approach, the thermodynamic databases, which are usually used to the calculation of phase diagrams of salt mixtures, can be applied to the evaluation of the surface tension of molten salt mixtures.
