| Hazard Information | Back Directory | [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]
Oxides of titanium find wide range of applications extending from photocatalysis, gas sensing to antibacterial, protective and anti-reflecting coatings. | [Uses]
Titanium(III) oxide is used to study the bioacceptability of medical implant surfaces. | [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)
