Legend

Name origin:	Greek: titanos (Titans)
Description:	Shiny, dark-gray metal. Ninth most abundant element in the earth's crust (5700 ppm). It can be highly polished, and is relatively immune to tarnishing.
Discovered by:	William Gregor
Year:	1791
Place:	England
Sources:	Usually occurs in the minerals ilmenite (FeTiO3) or rutile (TiO2). Also in Titaniferous magnetite, titanite (CaTiSiO5), and iron ores. Pure metal produced by heating TiO2 with C and Cl2 to produce TiCl4 then heated with Mg gas in Ar atmosphere.
Use(s):	Since it is strong and resists acids it is used in many alloys. Titanium dioxide (TiO2), a white pigment that covers surfaces very well, is used in paint, rubber, paper and many others.
