By the methods of molecular dynamics and continuous static relaxation, models for hypothetical 2MeO·SiO2 oxides with small-sized Me2 ions are synthesized. The models contain 497 particles in the basic cube each with periodic boundary conditions. The Borne-Meyer pair potentials are used with regard for Coulomb interaction by the Evald-Ansen method. The structural and configuration characteristics of the oxides are analyzed. The Gibbs energies, entropies, and component activities in the homologous series of 2MeO·SiO2 oxides are calculated.
