Titanium



The Reverend William Gregor in 1791, who was interested in minerals, discovered titanium.
He recognized the presence of a new element, now known as titanium, in menachanite, a
mineral named after Menaccan in Cornwall (England). Several years later, the element was
rediscovered in the ore rutile by a German chemist, Klaproth.

The pure elemental metal was not made until 1910 by Matthew A. Hunter, who heated TiCl4
together with sodium in a steel bomb at 700-800C.

Titanium is used for alloys with aluminum, molybdenum, manganese, iron, and other metals.
These alloys of titanium are used principally in the aerospace industry, for both
airframes and engines, where lightweight strength and ability to withstand extremes of
temperature are important. Titanium is as strong as steel, but much lighter. It is twice
as strong as aluminum. It is nearly as resistant to corrosion as platinum. Titanium is a
component of joint replacement parts, including hip ball and sockets.

It has excellent resistance to seawater and is used for propeller shafts, rigging, and
other parts of ships exposed to salt water. A titanium anode coated with platinum provides
cathodic protection from corrosion by salt water. Titanium paint is an excellent reflector
of infrared radiation, and is extensively used in solar observatories where heat causes
