Titanium

Titanium (Ti) is a silver metal that has the atomic number 22 in the periodic table. It is a Transition metal and located in Group 4 of the periodic table. It has the symbol Ti.

Titanium is a highly resistant transition metal with a low density and high strength. It exists in the earth’s crust combined with ores. It was discovered by Wiliiam Gregor in 1791 who recognised the element in the ore ilmenite which he was able to separate into the pure element titanium and oxides of iron, he however did not identify Titanium as an element. It was not until 1795 that the German chemist Martin Klaproth isolated pure Titanium and named it after the ‘Titans’ the sons of Greek gods. Titanium itself is used primarily in construction where often it is alloyed with Iron and Aluminium due to its strength and resistance to oxidation. It is also used in the construction of dental and medical devices. Due to its importance in construction it was a metal that during the cold war between the USSR and USA was stockpiled by both countries due to its strategic importance. Its compounds such as Titanium dioxide are commonly used as catalysts and also the production of white pigments, for example in sunscreen and paint. It is located in Group 4 and it has a melting point of 1688°c and a boiling point of 3287°c being a solid metal at room temperature.

FAQ's

What is the Melting Point for Titanium?

Titanium has a Melting Point of 1660°F, meaning at 1660°F it will turn to a liquid.

What is the Boiling Point for Titanium?

Titanium has a Boiling Point of 3287°F, meaning at 3287°F it will turn to a Gas.

What is the Electronegativity of Titanium?

Titanium's Electronegativty is 1.54. Electronegativity is a measure of how strongly atoms attract bonding electrons to themselves.

What is the Heat of Vaporization of Titanium?

Titanium has a Heat of Vaporization of 421 kJ/mol.

Uses

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.

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.

Transition metal is any of various chemical elements that have valence electrons (electrons that can participate in the formation of chemical bond) in two shells instead of only one. They form group 3 (IIIb) through group 12 (IIb).
