What is a rutile?
: a reddish-brown to black mineral that consists of titanium dioxide usually with a little iron and has a brilliant metallic or adamantine luster.
What is rutile used for in everyday life?
As a source of titanium dioxide pigment, rutile is used in plastics, paper products, paints, sunscreen, and even food coloring. Certain welding equipment also uses it.
Where is rutile most commonly found?
Rutile is commonly found in metamorphic rocks, such as eclogite. Rutile is also found as an accessory mineral in igneous rocks, particularly in deeper-formed plutonic igneous rocks and also volcanic rocks with deep sources, such as kimberlites. Rutile is an important economic mineral that is mined for titanium.
What is rutile in crystals?
Rutile, often referred throughout history as Red Schorl,is a rare titanium oxide mineral that crystallizes in the form of grains, masses, prismatic crystals and long needle like crystals. These needle shaped crystals can be found penetrating other minerals such as Quartz, Amethyst, and Hematite.
What is the characteristics of rutile?
Rutile has a very high refractive index, a strong dispersion, and an adamantine luster. These are optical properties that can produce a great gemstone, and these properties in rutile rival or exceed those of diamond.
Why is rutile white?
Rutile titanium dioxide (TiO2) white pigment has been prepared by doping and calcination of metatitanic acid (H2TiO3) obtained by the NaOH molten salt method.
What mineral is rutile?

How do I know if I have rutile?
Keys to identifying rutile are its strong yellowish to reddish brown color, high relief, and extreme birefringence. Color – Usually red, red-brown or yellowish-brown. May be pleochroic. Interference colors – Interference colors may not show due to the strong color of the mineral.
What is rutile in biology?
A lustrous red, reddish-brown, or black tetragonal mineral that is an ore of titanium. Rutile usually occurs as prismatic crystals in other minerals, especially as dark needlelike crystals in quartz.
What is the meaning of rutilant?
ru·tile (ro͞o′tēl′, -tīl′) n. A lustrous red, reddish-brown, or black mineral, TiO2, used as a gemstone, as an ore, and in paints and fillers.

Is rutile a metamorphic rock?
Rutile is a common accessory mineral in high-temperature and high-pressure metamorphic rocks and in igneous rocks . Thermodynamically, rutile is the most stable polymorph of TiO 2 at all temperatures, exhibiting lower total free energy than metastable phases of anatase or brookite.
What is the difference between rutile and titanium?
rutile- a mineral consisting of titanium dioxide in crystalline form; occurs in metamorphic and plutonic rocks and is a major source of titanium atomic number 22, Ti, titanium- a light strong grey lustrous corrosion-resistant metallic element used in strong lightweight alloys (as for airplane parts); the main sources are rutile and ilmenite
