Abstract
A semi-empirical equation, based on simple regular solution theory and involving only dispersion and charge–dipole interactions, is deduced for the excess enthalpy, HE, of a family of molten salt mixtures. The hard-core separation, λ, calculated from scaled particle theory, is adopted for the anion-cation separation in the melt. When the excess enthalpies at the equimolar composition, calculated from the derived equation, are compared with the experimental HE values available for 37 of the possible 40 binary alkali halide mixtures with a common anion, almost perfect agreement is obtained.
