CHEMISTRY

= <> = A chemical element inside the transition metals and is part of Group 4 (IVB). Symbol: Ti Atomic number: 22 Atomic mass: 47 electron shells: 4

 Sometimes called the “space age metal”, it has a low density and can be [|alloyed] with [|iron], [|aluminium] , [|vanadium] , etc. Titanium was discovered in England by [|William Gregor] in 1791 and named by [|Martin Heinrich Klaproth] for the [|Titans] of [|Greek mythology].

This metal is extracted from its principal mineral ores by the [|Kroll process] or the [|Hunter process].

The two most useful properties of the metal form are corrosion resistance and the highest strength-to-weight ratio of any metal.

Titanium's properties are chemically and physically similar to [|zirconium]. Titanium is the 9th most abundant element in the earth's crust.

It is almost always found in igneous rocks.Titanium is found in coal ash, plants, and in the human body.Titanium is found in the sun and in meteorites. Rocks from the Apollo 17 mission to the moon contained up to 12.1% TiO2. Rocks from earlier missions showed lower percentages of titanium dioxide. Titanium oxide bands are seen in spectra of M-type stars. In 1946, Kroll showed that titanium could be produced commercially by reducing titanium tetrachloride with magnesium.
