Tóm tắt

The thermodynamic stabilities of titanium oxides in the composition range TiO-TiO2, including Ti2O3, Ti3O5, and the homologous series Ti n O2n − 1 (n = 4–10), are compared by physicochemical simulation using the program package Selektor. The oxide composition is correlated with the states of titanium and oxygen in the oxide lattice. The phase transitions and chemical reactions in the oxides depend on the medium (air or water).
