Titanium(III) oxide is the inorganic compound with the formula Ti2O3. A black semiconducting solid, it is prepared by reducing titanium dioxide with titanium metal at 1600 °C.[3]

Quick Facts Names, Identifiers ...

Ti2O3 adopts the Al2O3 (corundum) structure.[3] It is reactive with oxidising agents.[3] At around 200 °C, there is a transition from semiconducting to metallic conducting.[3] Titanium(III) oxide occurs naturally as the extremely rare mineral in the form of tistarite.[4]

Other titanium(III) oxides include LiTi2O4 and LiTiO2.[5]
