| Mineral Name: | Anatase |
| Composition: | Titanium oxide |
| Nomenclature: | Named after the Greek word anatasis, meaning "elongation," a reference to the shape of the crystals. |
| Industrial Uses: | Ore of titanium. |
| Additional Notes: | Anatase is a polymorph with two other minerals, brookite and rutile. Polymorphs (a term that means "multiple forms") are minerals that have the same chemical composition—titanium oxide in the case of anatase, brookite, and rutile—but have different crystallographic structures. Anatase is also known as octahedrite. |
