It is a mineral composed primarily of titanium dioxide.the most common natural form of TiO2, and it is found as an accessory mineral in some altered igneous rocks, and in certain gneisses and schists.
The main uses for Rutile (CAS NO.1317-80-2) are the manufacture of refractory ceramic, as a pigment, and for the production of titanium metal.Finely powdered rutile is a brilliant white pigment and is used in paints, foods, plastics, paper, and other applications that call for a bright white color. Titanium dioxide pigment is the single greatest use of titanium worldwide. It is widely used as a welding electrode covering.
In 2005 ,the Republic of Sierra Leone in West Africa had a production capacity of 23% of the world's annual Rutile supply, which rose to approximately 30% in 2008. The reserves, lasting for about 19 years, are estimated at 259,000,000 metric tons (285,000,000 short tons).

Synthetic Rutile (CAS NO.1317-80-2) was first produced in 1948 .Very pure synthetic rutile is transparent and almost colorless (slightly yellow) in large pieces. It can be made in a variety of colors by doping, although the purest material is almost colorless. The high refractive index gives an adamantine lustre and strong refraction that leads to a diamond-like appearance. The near-colorless diamond substitute is sold under the name Titania .
