Rutile

Rutile is a mineral composed of titanium dioxide (TiO2) and is one of the three naturally occurring forms of titanium dioxide. It is commonly found in igneous rocks, metamorphic rocks, and sedimentary rocks. Rutile is a hard and dense mineral, with a specific gravity of 4.2 and a Mohs hardness of 6-6.5. It is also known for its high refractive index, making it useful in the production of optical lenses and as a coating for optical instruments.

Rutile is primarily used as a source of titanium dioxide, which has a wide range of applications in various industries. It is commonly used as a pigment in paints, plastics, and paper, as well as in the production of ceramics, glass, and rubber. Rutile is also used in the production of titanium metal, which is used in aerospace, military, and medical applications due to its strength, lightness, and resistance to corrosion. Additionally, rutile is used as a welding electrode coating and as a catalyst in the production of chemicals.
