titanium dioxide anatase

Anatase is one of three most common mineral forms of titanium dioxide (TiO 2), the other two being brookite and rutile. Anatase and rutile are similarly abundant, but easily distinguishable on the basis of habit (anatase displays steeper pyramidal faces), hardness, density and luster (anatase is softer, lighter and more metallic).

Anatase is one of the three primary mineral forms of titanium dioxide (TiO2), the other two being rutile and brookite.
