Titanium is a chemical element with the symbol Ti and atomic number 22. It is a brilliant transition metal with a silvery color, low density, and high strength. Titanium is corrosion resistant in seawater, water regime, and chlorine.
Titanium was discovered in Cornwall, Great Britain by William Gregor in 1791, and was named by Martin Heinrich Klaproth for the titans of Greek mythology. The element is within a range of minerals, particularly rutile and ilmenite deposits, which are widely distributed in the crust and the Earth’s lithosphere, and is found in almost all living things, bodies of water, rocks, and soils. The metal is extracted from its main mineral minerals by the processes of Kroll and Hunter.
