Titanium: the essentials

Titanium atoms have 22 electrons and the shell structure is 2.8.10.2. The ground state electronic configuration of neutral titanium is [Ar].3d2.4s2 and the term symbol of titanium is 3F2.

Titanium: description  

Titanium s a lustrous, white metal when pure. Titanium minerals are quite common. The metal has a low density, good strength, is easily fabricated, and has excellent corrosion resistance. The metal burns in air and is the only element that burns in nitrogen. It is marvellous in fireworks.

Titanium is resistant to dilute sulphuric and hydrochloric acid, most organic acids, damp chlorine gas, and chloride solutions. Titanium metal is considered to be physiologically inert.

Titanium is present in meteorites and in the sun. Some lunar rocks contain high concentrations of the dioxide, TiO2. Titanium oxide bands are prominent in the spectra of M-type stars.

Titanium: isotopes

Isotope abundances of titanium
Isotope abundances of titanium with the most intense signal set to 100%.

The five stable Titanium isotopes are used for a wide range of studies and applications. Ti-48 is used for the production of the radioisotope V-48 which is used in nutritional studies and for calibrating PET instrumentation. Ti-47 is occasionally used as an alternative precursor for the production of V-48. Ti-50 is used in the production of super heavy elements whereby Lead or Bismuth targets are bombarded with Ti-50. Finally, Ti-49 is used in the production of the radioisotope V-49.

Titanium: isolation

Isolation: titanium is readily available from commercial sources so preparation in the laboratory is not normally required. In industry, reduction of ores with carbon is not a useful option as intractable carbides are produced. The Kroll method is used on large scales and involves the action of chlorine and carbon upon ilmenite (TiFeO3) or rutile (TiO2). The resultant titanium tetrachloride, TiCl4, is separated from the iron trichloride, FeCl3, by fractional distillation. Finally TiCl4 is reduced to metallic titanium by reduction with magnesium, Mg. Air is excluded so as to prevent contamination of the product with oxygen or nitrogen.

2TiFeO3 + 7Cl2 + 6C (900°C) → 2TiCl4 + 2FeCl3 + 6CO

TiCl4 + 2Mg (1100°C) → 2MgCl2 + Ti

Excess magensium and magneium dichloride is removed from the product bytreatment with water and hydrochloric acid to leave a titanium "sponge". This can be melted under a helium or argon atmosphere to allow casting as bars.
