Synthetic rutile can be made by the Verneuil process in a variety of colors, including brown, yellow, red, and blue. Completely colorless stones cannot, however, be produced and always have a tinge of yellow. The colored varieties were seldom seen in the gem trade. Rutile is too soft to be useful as a gemstone (hardness 6-6.5 on the Mohs scale).

Rutile is primarily composed of titanium dioxide. Synthetic rutile is produced from naturally-occurring ilmenite, which is a complex oxide of iron. Synthetic rutile is used as a byproduct of titanium dioxide. Synthetic rutile can be made of different colors by the doping method.

Synthetic rutile (TiO 2) is manufactured through the upgrading of ilmenite ore to remove impurities (mostly iron) and yield a feedstock for production of titanium tetrachloride through the chloride process. The chemical composition of synthetic rutile is similar to that of natural rutile, but differs in physical form. Synthetic rutile

The Becher process is an industrial process used to produce rutile, a form of titanium dioxide, from the ore ilmenite.It is competitive with the chloride process and the sulfate process, which achieve similar net conversions.. With the idealized formula FeTiO 3, ilmenite contains 55-65% titanium dioxide, the rest being iron oxide.The Becher process, like other beneficiation processes, aims to ...

The chemical formula of synthetic rutile is TiO 2, and it crystallizes in the tetragonal system in boules similar to those of synthetic corundum. The specific gravity is 4.24 to 4.26. The hardness, as mentioned previously, is approximately 6; it is usually given by the manufacturers as 6 to 6-1/2, but it is relatively easily scratched and fractured by a 6 hardness point.

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.
