2.Titanium History
Titanium was first discovered in an impure form by Rev. William Gregor in England, 1791. It was later given
the name titanium (after the Titans, in Greek mythology, the sons of the sky and Earth gods) by a German
chemist., Martin Kloproth, when he found a dioxide of the metal in rutile, ilmenite and in many other widely
dispersed ores.
In 1910, pure titanium was manufactured by M.A. Hunter, an American chemist. Hunter was able to extract the
metal from the ores and developed the process of mixing rutile ore(TiO2) with chlorine and coke, then
applying extreme heat, producing titanium tetrachloride(Ticl4), witch was further reduced with sodium to form
titanium.The hunter process successfully prodeced high quality titanium.
Dr.Wilhelm Kroll, in 1946, developed the process currently used for producing titanium commercially.The
Kroll process reduces titanium tetrachloride(TiCl4) with magnesium.This multi-batch, high temperature
process proves to be inefficient. It drives the price of titanium to the point where its applications are
restricted to the high-priced, niche markets.
