| Description |
On the basis of mathematical models of the formation of solid solutions in the In2O3 – ТіО2 calculated ionic radius of the cations: indium, titanium, anion and anionic vacancies on the scale of Templeton and Deben. A phase transformation in the oxide of indium was related with disorder of anionic vacancies in the lattice type C. The formation of solid solutions in this system proceeds on the basis of the disordered phase of type С1. The system formed limited solid solutions such as: subtraction – substitution – inculcation of a range of concentrations (0 – 2% ТіО2), subtraction – substitution of concentrations (0.5 – 2% іО2), higher concentrations of these compounds present in the mixture of In2TiO5-х – rhombic modification, which is formed during sintering the samples at 1100 ·C in air. The type solid solution systems in the In2O3 – ТіО2, depend on the size of cation bases and additives. The energies of formation: solid solution subtraction – substitution – introduction, solid solution subtraction – substitution were determined and shows that the conductivity of the current, concentration and mobility of the charge carriers depends on the type of the solid solution and not on the valence of the dissolved additive.
