The mathematical model for the simulation of the formation and dissociation processes of solid solutions in In2O3-ZrО2 system are proposed. It permit us to calculate the ionic radii of cations: indium, zirconium, anion and anion vacancy. Solid solutions in the system formed by the disordered phase of indium oxide type C1. It was revealed that at temperatures 1450, 1600° C in air d of the system formed limited solid solutions such as: subtraction – substitution, subtraction – replacement – introduction. It was established, the size of the cations of indium, zirconium, and the number of defects determines the type of solid solution in the system In2O3-ZrО2. The energies of the formation of solid solutions, energy of the electrical conductivity in this system were calculated. Using the sale conductivities data it was revealed that the conduction current density and charge carrier mobility depends on the type of solid solution, rather than on the valence of the cations of zirconium.
