摘要
A pair interaction model applying the Bragg-Williams approach is presented. The formalism is given in a general form; ternary ordered compounds with different crystal structures and all possible point defect types are considered. Some applications are discussed. The Bragg-Williams approach is an easily applicable formalism that leads -proper use supposed-to accurate predictions concerning thermodynamic data as well as defect concentrations.
