Titanium dioxide TiO₂

Titanium dioxide

- also known as titanium(IV) oxide or titania, is the naturally occurring oxide of titanium, chemical formula TiO2. When used as a pigment, it is called titanium white, Pigment White 6, or CI 77891. It is noteworthy for its wide range of applications, from paint to sunscreen to food colouring when it is given the E number E171.

Titanium dioxide occurs in nature as the well-known naturally occurring minerals rutile, anatase and brookite, additionally two high pressure forms, the monoclinic baddeleyite form and the orthorhombic α-PbO₂ form have been found at the Ries crater in Bavaria. The most common form is rutile, which is also the most stable form. Anatase and brookite both convert to rutile upon heating.

Rutile, anatase and brookite all contain six coordinate titanium. Additionally there are three metastable forms produced synthetically and five high pressure forms.

We are ready to export Titanium dioxide TiO₂, fraction of total mass, % not less than 99.999 of the brand SUM TITAN R 203, from the manufacturer.
