A comprehensive approach has been developed for the construction of theoretical models of ordered alloys of ternary systems based on Bi-Cd-Sb. A diagram of distribution of phase regions and isothermal sections based on intermediate binary compounds Bi-Cd, Bi-Sb, Cd-Sb in the Bi-Cd-Sb system have been constructed. Calculations of effective radii, redistribution of electron density and dissociation energy of non-equivalent chemical bonds depending on interatomic distances in the Bi-Cd-Sb ternary system are presented.
