ANATASE

Anatase is a metastable mineral form of titanium dioxide (TiO2) with a tetragonal crystal structure. Although colorless or white when pure, anatase in nature, is usually a black solid due to impurities. Three other polymorphs (or mineral forms) of titanium dioxide are known to occur naturally. They are brookite, akaogiite, and rutile, with rutile being the most common and most stable of the bunch. Anatase is formed at relatively low temperatures and found in minor concentrations in igneous and metamorphic rocks

Another name commonly used for Anatase is octahedrite

USES

Anatase Titanium dioxide is extensively used in plastics, ink, coatings, paper, rubber, chemical fiber, chemical, ceramics, pharmaceutical, food, and some further industries.

WHERE TO FIND

Anatase is a relatively rare mineral found in veins and cavities in schists, gneisses, granites, syenites and other related igneous rocks. It is also a product of weathering of other titanium minerals.

Deposits have been found in the Alps, Brazil, and the Ural Mountains.
