Commercially important titanium mineral (titanium dioxide, TiO2). It forms red to reddish brown, hard, brilliant metallic, slender crystals. Rutile has minor uses in porcelain and glass manufacture as a colouring agent and in making some steels and copper alloys. It is also used as a gem, but synthetic rutile is actually superior to natural crystals for gem use; it has fire (flashes of colour) and brilliance (light deflection) like those of diamond. Rutile is mined in Norway and is widespread in the Alps, the southern U.S., Mexico, and elsewhere
A mineral usually of a reddish brown color, and brilliant metallic adamantine luster, occurring in tetragonal crystals
A titanium mineral [TiO2] widespread as an accessory in igneous and metamorphic rocks It is also common in beach sands
a mineral consisting of titanium dioxide in crystalline form; occurs in metamorphic and plutonic rocks and is a major source of titanium
the most frequent of the three polymorphs of titanium dioxide, crystalizing in the tetragonal system
A natural mineral, theoretically containing 100% TiO2 Actual TiO2 content varies from 92% - 96%
