Titanium(III) oxide Chemical Properties, Uses, Production

Chemical Properties

violet sintered tablets; hexagonal; oxidizes to TiO2; sintered material of 99.9% purity used as an evaporation material for interference films, thin film resistors and capacitors [KIR83] [CER91]

Physical properties

Dark-violet to purple-violet solid. It can be prepared by mixing stoichiometric amounts of Ti and TiO2 heated in a Mo-crucible at 1600°C. Slightly paramagnetic solid  with χm = +63 × 10–6 emu.

Uses

Titanium(III) oxide is used to study the bioacceptability of medical implant surfaces.

Uses

Oxides of titanium find wide range of applications extending from photocatalysis, gas sensing to antibacterial, protective and anti-reflecting coatings.

Preparation

Titanium sesquioxide(Ti2O3) has a corundum structure and is isomorphous with hematite and ilmenite. It may be prepared by reduction of titania by hydrogen gas at 1000°C or as powder by reacting titanium metal with a stoichiometric amount of TiO2 at 1600°C as follows:
Ti(s) + 3TiO2(s) —> 2 Ti2O3(s) (1600°C)

reaction suitability

reagent type: catalyst
core: titanium
