Titanium is a chemical element with the symbol Ti and an atomic number of 22. Compared to other metals, it is a lustrous and silver transition metal with low density and high corrosion resistance to sea water, aqua regia and chlorine, etc..
Titanium history
Titanium was discovered by amateur geologist William Gregor. Four years later, German chemist Martin Heinrich Klaproth independently discovered the new element in rutile and named it after the Titans of Greek mythology.
Pure metallic Titanium (99.9%) was first obtained in 1910 by Matthew A. Hunter at Rensselaer Polytechnic Institute by heating the mixture of TiCl4 and Sodium at 700-800°C. In 1932 William Justin Kroll proved that Titanium metal could be produced by reducing Titanium Tetrachloride (TiCl4) with Calcium. Eight years later he refined this process by using Magnesium and even Sodium, which was known later as the Kroll process.
