Rutile - Wikipedia

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.

synthetic rutile or titaniferous slag. Ideal rutile contains about 95 percent TiO 2, but it is usually less abundant than ilmenite in HMS deposits. Although numerous technologies are used to produce synthetic rutile, nearly all are based on either selective leaching or thermal reduction of iron and other impurities in ilmenite (Bedinger, 2013a).

However, a natural rutile or synthetic rutile (SR) with a TiO 2 content of at least 88% is required in the chlorination process. Since the reserves of natural rutile is only one-tenth of the ilmenite reserves, development of various synthetic rutile preparation technologies using ilmenite has been attracting widespread attention.

Synthetic rutile. Synthetic rutile, first produced in 1948 by the Verneuil process, is far superior to the natural material as a gemstone, because natural rutile is dark in colour and the pure synthetic boules may be produced in nearly any shade by the addition of appropriate pigments.
