Statistical thermodynamics of multicomponent systems (mixtures) in the quasilattice coordination approximation

Based on the well-known concepts of statistics of nearest neighbors in a lattice and on the BethePeierls-Guggenheim quasichemical approximation, combination rules are obtained allowing us to express the thermodynamic functions of multicomponent systems (mixtures) with given chemical and coordination composition in terms of thermodynamic functions of the pure subsystems. © 1977 Plenum Publishing Corporation.
