酸化チタン()

化学的特性

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]

物理的性質

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 χ_m = +63 × 10^–6 emu.

使用

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

製造方法

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)
