, 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.Occurrence[සංස්කරණය]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. [1][2] The most common form is rutile[3], which is also the most stable form. Anatase and brookite both convert to rutile upon heating.[3] Rutile, anatase and brookite all contain six coordinate titanium. Additionally there are three metastable forms produced synthetically and five high pressure forms:FormCrystal systemSynthesisrutiletetragonalanatasetetragonalbrookiteorthorhombicTiO2(B)[4]mon
