What is Titanium Dioxide ?
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 has a wide range of applications, from paint to sunscreen to food colouring. Titanium dioxide is a naturally occurring oxide of the element titanium.
Also referred to as titanium (IV) oxide or titania, this substance also occurs naturally as three mineral compounds known as anatase, brookite, and rutile. As a pigment, titanium dioxide is used to enhance the white color of certain foods, such as dairy products and candy. Titanium dioxide occurs in nature as well-known minerals rutile, anatase and brookite, and additionally as two high pressure forms, a monoclinic baddeleyite-like form and an orthorhombic ?-PbO2-like form, both found recently at the Ries crater in Bavaria. Rutile, anatase and brookite all contain six coordinated titanium.
