Abstract

Titanium has not been found in a free state in nature. It is a greyish metal and resembles tin in its chemical properties and, like that metal, is capable of forming two oxides, TiO and TiO2. Only the latter occurs in nature; it supplies an example of trimorphism, constituting the three distinct minerals, rutile, anatase and brookite. Titanium oxide also enters into the composition of ilmenite, the oxide of titanium and iron, FeTiO3, and many samples of magnetite contain varying amounts of titanium, giving the titaniferous magnetites. At the present time, ilmenite is the chief source of the titanium required in industry, whilst the employment of this mineral as an iron ore proper is not yet possible—accordingly ilmenite is described here with the other titanium minerals. Titanium occurs in a number of rock-forming silicates, the chief of which is sphene or titanite, CaTiSiO5, described on p. 363.
