チタン(II)オキシド 化学特性,用途語,生産方法
化学的特性
Titanium monoxide, TiO, has a rock-salt structure but can exist with both oxygen and titanium vacancies. For stoichiometric TiO, the lattice parameter is 417 pm, but varies from ca 418 pm at 46 atom % to 4162 pm at 54 atom % oxygen. Apparently, stoichiometric TiO has ca 15% of the Ti and O sites vacant. At high temperatures (>900 °C (1,652 °F)), these vacancies are randomly distributed; at low temperatures, they become ordered. Titanium monoxide may be made by heating a stoichiometric mixture of titanium metal and titanium dioxide powders at 1,600 °C (2,912 °F).

–6 emu.
使用
Used for vacuum deposition. Also applications include sunscreens and UV-blocking in cosmetics, varnishes, wood preservatives, textile fibers, and packaging films. Also used as paint pigment, opacifying agent, welding rod fluxes, optical coatings, as a catalyst, ceramic finish coat, plastics, elastomers, coated fabrics, printing inks, roofing granules, glass, and in glazes. Also identified as Titanium monoxide.
製造方法
Titanium monoxide or hongquiite (TiO) may be prepared by direct reduction by mixing stoichiometric amounts of titanium metal
and titanium dioxide into a molybdenum crucible at 1600°C or reduction of the titanium
dioxide with hydrogen under pressure at 130 atm and 2000°C.
