Titanium

                         TITANIUM
Name:Titanium
Simble:Ti
Atomic number:22
Melting point:1660°C
Boiling point:3560°C
Colour: Silvery metallic
Classification: Metallic




Titanium s a lustrous, white metal when pure. Titanium minerals are quite common. The metal has a low density, good strength, is easily fabricated, and has excellent corrosion resistance. The metal burns in air and is the only element that burns in nitrogen. It is marvellous in fireworks.
Titanium is resistant to dilute sulphuric and hydrochloric acid, most organic acids, damp chlorine gas, and chloride solutions. Titanium metal is considered to be physiologically inert.






Titanium: historical information

Titanium was discovered by William Gregor at 1791 in England. Origin of name: named after the "Titans", (the sons of the Earth goddess in Greek mythology).
Titanium was discovered by the Reverend William Gregor in 1791, who was interested in minerals. 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 TiCl4together with sodium in a steel bomb at 700-800°C.
