William Gregor – discoverer of titanium metal

William Gregor

Biography & contributions

William Gregor, British clergyman, and mineralogist born on December 25, 1761 – died on June 11, 1817. Gregor was well known for discovering titanium periodic table transition metal element.

Gregor later found titanium in corundum from Tibet, and in a tourmaline from a menaccanite mineral. It was not until 1795 that M. H. Klaproth, on analyzing futile, called the new metal Titanium or Titankalk, and on subsequently analyzing menaccanite and finding it contained the same metal, he graciously acknowledged Gregor's prior claim to the discovery.

Facts about titanium

Titanium is classified as a transitional metal. Titanium is the ninth most abundant element in Earth’s crust. It is almost always present in igneous rocks and their sediments. Pure titanium is a lustrous white metal. It is strong, light with low density, and has excellent corrosion resistance.

Titanium is as strong as steel but 45 percent lighter. It is 60 percent heavier than aluminum but twice as strong. It is widely distributed and occurs primarily in the minerals anatase, brookite, ilmenite, perovskite, rutile, and titanite. Titanium is contained in meteorites and has been detected in the sun and in M-type stars.

It is ductile only when free of oxygen. Titanium metal is the only element that burns in nitrogen. Titanium is fairly hard non-magnetic and a poor conductor of heat and electricity. Titanium is one of the few elements that burn in pure nitrogen gas, reacting at 800 °C (1,470 °F) to form titanium nitride, which causes embrittlement.

Titanium is found in space and on Earth. It is present in meteorites, the sun, and M-type stars. Rocks from Apollo lunar missions showed the presence of titanium.

Titanium metal is used in automotive applications, particularly in automobile or motorcycle racing, where weight reduction is critical while maintaining high strength and rigidity. It is also used in cement, in gemstones, as an optical opacifier in the paper. Titanium is used in many sporting goods: tennis rackets, golf clubs, lacrosse stick shafts; cricket, hockey, lacrosse, and football helmet grills.
