Synthetic rutile can be produced from naturally occurring ilmenite which is a complex oxide with iron. Rutile is used in the manufacture of titanium dioxide pigment. In Australia most rutile is produced from ilmenite as it naturally occurs in accessible high concentrations and in a form which allows the ready extraction of the rutile.

The name rutile was first introduced by the German geologist Abraham Gottlob Werner in 1800 (cfr. Lampadius 1800 and Ludwig 1803). The name is from the Latin rutilus, meaning "reddish."The mineral was already known under other names, such as "red schorl" and some other names, some of them later recognized as synonyms or varieties.

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. Consequently, the transformation of the metastable TiO 2 polymorphs to rutile is irreversible.

Deposition can be improved through the addition of iron powder, which leads to more metal being deposited at the same current. However, electrodes with added iron powder can only be used in a flat position. Rutile electrodes have a medium penetration, quiet arc and create little spatter (Bosward, 1980).
