Titanium dioxide, also known as titanium(IV) oxide or titania, is thenaturally occurring oxide of titanium, chemical formula TiO2.
Rutile is a mineral composed primarily of titanium dioxide, TiO2.
Rutile is the most common natural form of TiO2, with two rarerpolymorphs anatase (sometimes known by the obsolete name'octahedrite'), a tetragonal mineral of seudo-octahedral habit; andbrookite, an orthorhombic mineral. Rutile has among the highestrefractive indices of any known mineral and also exhibits highdispersion. Natural rutile may contain up to 10% iron and significantamounts of niobium and tantalum.
Rutile, when present in large enough quantities in beach sands, formsan important constituent of heavy mineral sands ore deposits. It isprimarily extracted for use in refractory manufacture or use as a basefor paints. Rarely is it extracted as an ore of titanium.
Finely powdered rutile is a brilliant white pigment and is used inpaints, plastics, papers, foods, and other applications that call for abright white color. Titanium dioxide pigment is the single greatest useof titanium worldwide. Nanoscale particles of rutile are transparent tovisible light but are highly effective in the absorption of UV light.The UV absorption of nano-sized rutile particles is blue-shiftedcompared to bulk rutile, so that higher energy UV light is absorbed bythe nano particles. Hence, they are used in sunscreens to protectagainst UV induced skin damage.
Small rutile needles present in gems are responsible for an opticalphenomenon known as asterism. Asterated gems are known as "star" gems.Star sapphires, star rubies, and other "star" gems are highly soughtafter and often more valuable than their normal equivalents.
Rutile is widely used as a welding electrode covering.
