Solubility and the Nature of Bonding in Fused Alkali Halide-Metal Systems

A solution of an alkali metal in a fused halide of the same metal is discussed in terms of the mixing of the two negative species, halide ions and F- center-like electrons in cavities, within the irregular lattice of positive ions. The positive energy of mixing is related to the excess energy of a hypothetical metal comprising an ionic lattice of F-centers and positive ions over that of the true metal. The theory predicts substantial positive excess entropies of mixing. The solubility data of Bredig and collaborators are shown to be consistent with this model and certain parameters are evaluated for each system.
