Composition and aggregative state of the products of TiO2 heating in argon atmosphere

Compositions of condensed matter are calculated using thermodynamic modeling methods taking into account the existence of solid and liquid solutions from TiO ₂ , TiO, Ti ₂ O ₃ , Ti ₃ O ₅ and Ti ₄ O ₇ , as well as partial pressures {TiO ₂ }, {TiO}, {Ti}, {O ₂ }, {O}, formed by heating the starting titanium dioxide in argon at a pressure of 9.8066 x; 10 ^-2 MPa in the temperature range 300 - 2485 K. The results obtained can be useful in describing chemical transformations occurring under conditions of high-temperature synthesis of complex types of ceramics with the participation of titanium dioxide, and in analyzing their composition.
