Titanium(II) oxide
Titanium dioxide, chemical formula TiO2, commonly known as titanium dioxide, used for the photocatalyst, cosmetics, can rely on UV disinfection and sterilization, are now widely developed in the future have the opportunity to become the new industry. Titanium dioxide can be rutile extracted with acid decomposition, or decomposed by the titanium tetrachloride. The nature of the stability of titanium dioxide, used as white pigment in the paint a lot of it has good covering power, and similar to white lead, but unlike the white lead black; it with zinc white and persistence. Titanium dioxide is also used as the enamel of the matting agent can produce a very bright, hard and acid resistance of enamel overlay.
Characters
A white amorphous powder. Dissolved in hydrofluoric acid and hot concentrated sulfuric acid, insoluble in water, hydrochloric acid, nitric acid and dilute sulfuric acid. With potassium hydrogen sulfate or alkali hydroxide or alkali carbonate melt into a titanium acid-base soluble in water. The relative density of about 4.0. The melting point of 1855 ℃.
Store
Sealed and stored.
Titanium(II) oxide (TiO) is an asleep actinic admixture of titanium and oxygen. It can be able from titanium dioxide and titanium metal at 1500°C. It is non-stoichiometric in a ambit TiO0.7 to TiO1.3 and this is acquired by vacancies of either Ti or O in the birthmark bedrock alkali anatomy (chalk). In authentic TiO 15% of both Ti and O sites are vacant. Careful annealing can could cause acclimation of the vacancies bearing a monoclinic anatomy which has 5 TiO units in the archaic corpuscle that exhibits college resistivity There is aswell a top temperature anatomy with titanium atoms with trigonal bright coordination. Acid solutions of TiO are abiding for a abbreviate time again decompose to accord hydrogen:
Ti2+ + H+ → Ti3+ + ½ H2
