    Isothermal heating of the equimolar mixture of titanium monoxide (TiO) and ferric oxide (Fe2O3) or magnetite (Fe3O4) in a vacuum at 1000 oC results in solid state formation of Fe, FeO, Fe3O4, Ti4O7 and TiO2, FeTiO3 and Fe2TiO4, which is consonant with simultaneously occurring reductive Fe2O3 → Fe3O4 → FeO → Fe and oxidative TiO → Ti2O3 → TinO2n-1 → TiO2 paths and subsequent bonding of FeO and TiO2 oxides. The reducing action of TiO towards iron oxides suggests that TiO may also reduce other solid oxides and lead to formation of novel titania-containing materials.
