Titanium is moderately reactive, forming tetravalent compounds, including titanates (TiO32-), and less stable di- and tri-valent compounds.
Discovery of titaniumIn 1791, the Reverend William Gregor, an English clergyman and mineralogist, reported that he had discovered a magnetic black sand near the beaches of Cornwall, England. The mineral was named menachanite after the local parish of Menaccan. A few years after Gregor's discovery, Martin Klaproth, a German chemist, separated titanium dioxide (TiO2) from the mineral rutile. Klaproth named the new element titanium after the giants of Greek mythology. In 1825, Jöns Berzelius performed a crude separation of titanium metal. However, it was not until 1910 that M. A. Hunter, an American chemist, produced pure titanium. W. J. Kroll patented his method for producing titanium metal in 1938. Coincidently, commercial production of titanium metal and titanium dioxide pigment began in the 1940s.

Titanium compoundsTitanium (IV) oxide (TiO2) is used as a white pigment in paints, ceramics, etc. Titanium (IV) chloride (TiCl4) finds use as a catalyst.
