Etymology

Description

It is a white transition metal. It is found in many minerals. It is used in wear-resistant, strong and lightweight alloys. When exposed to air, it forms a passive oxide coating on its outer surface. It was first discovered by Gregor in 1789.

Production & Use

Sources

It is usually found in minerals such as ilmenite (FeTiO3) and rutile (TiO2). It is also seen in titanium magnetite, titanite (CaTiSiO5) and iron ores. To obtain the pure metal state, titanium dioxide (TiO2) is first heated with carbon (C) and chlorine (Cl2) to obtain titanium tetrachloride (TiCl4). Then, this compound is heated in an argon atmosphere, this time with gaseous magnesium.

Uses

It is used in many alloys because it is chemically strong and resistant to acids. Titanium dioxide (TiO2), a white pigment that covers surfaces very well, is used in paints, rubber, papers and many other materials.
