An anatase is a blue or brown mineral, a form of titanium dioxide, used as a pigment.
Nano anatase and nano rutile are both forms of titanium dioxide nanoparticles, but they have different crystal structures. Anatase has a tetragonal structure, while rutile has a more compact orthorhombic structure. These structural differences can affect their physical and chemical properties, such as reactivity, stability, and optical properties.
Brookite is primarily found in regions with metamorphic or pegmatitic rocks, such as Switzerland, Brazil, Pakistan, and the United States (Colorado and Arkansas). It is often associated with other titanium minerals like rutile and anatase.
Bauxite consists of goethite, hematite, gibbsite, boehmite, diaspore, kaolinite, and anatase.
Rutile, TiO2, is an oxide. An interesting mineral, most unusual for being trimorphous with anatase and rutile.

One of the rarest minerals ever found is painite. Painite was first discovered in Myanmar in the 1950s and is a borate mineral with a unique reddish-brown to orange color. It is extremely rare, with only a handful of known specimens in existence.
Titanium ores can occur as ilmenite, rutile, and titanium dioxide minerals such as brookite and anatase. These ores are typically found in beach sands, placer deposits, and igneous rocks.
Titanium oxide is also called titanium dioxide. It is a compound and occurs in the minerals rutile, anatase and brookite.
Titanium dioxide is found in a wide range of products, including sunscreen, cosmetics, paints, and food products as a pigment or whitening agent. It is also naturally occurring in the earth's crust as a mineral called rutile or anatase.
Paints (indoor): This is the most common. Paper: for writing and printing. Ceramics: pigmentations. Food: food colouring. It's not too useful outdoors because it has a lower absorbance than rutile.
