Rutile is an oxide mineral composed of titanium dioxide (TiO 2), the most common natural form of TiO 2. Rarer polymorphs of TiO 2 are known, including anatase , akaogiite , and brookite . Rutile has one of the highest refractive indices at visible wavelengths of any known crystal and also exhibits a particularly large birefringence and high ...
Rutile is the next most abundant and contains around 98% titanium dioxide in the ore. The metastable anatase and brookite phases convert irreversibly to the equilibrium rutile phase upon heating above temperatures in the range 600–800 °C (1,110–1,470 °F). [14]
The chloride process is used to separate titanium from its ores. The goal of the process is to win high purity titanium dioxide from ores such as ilmenite (FeTiO 3) and rutile (TiO 2). The strategy exploits the volatility of TiCl 4, which is readily purified and converted to the dioxide.
Rutilated quartz used as a gemstone. Rutilated quartz is a variety of quartz which contains acicular (needle-like) inclusions of rutile. [1] It is used for gemstones. These inclusions mostly look golden, but they also can appear silver, copper red or black.
Rutile also forms as slender crystals within quartz and micas. It is a common mineral in the alluvial sands that are dredged for magnetite and ilmenite. Rutile is used as a coating on welding rods. It is also used as an ore of titanium, a metal used where light weight and high strength are needed.

The Becher process is an industrial process used to produce synthetic rutile, a form of titanium dioxide, from the ore ilmenite. The Chloride process. The Sulfate process: "relies on sulfuric acid (H2SO4) to leach titanium from ilmenite ore (FeTiO3). The resulting reaction produces titanyl sulfate (TiOSO4). A secondary hydrolysis stage is used ...
Use a cut-up milk jug as a pet food scoop or outside for scooping soil or plant fertilizer. It’s pretty simple to make one, according to Family Handyman . Just make a line on the jug and cut it ...
