摘要：

A statistical theory for the composition dependence of the heat of formation of alkali halide solid solutions has been developed on the basis of the substitutional impurity model of Dick and Das. Numerical results are presented for all pairs of binary alkali halide systems. Good agreement with experimental values is found over the entire composition range for seven out of eight systems for which experimental data are available. The overall agreement is better than for any of the previously developed theories of other authors. © 1969.
