Density:4.50 g/cm3
Melting point: 1941 K (1668 oC)
Boiling point: 3560 K (3287 oC)
Discovered:
Titanium was discovered by the Reverend William Gregor in 1791. The pure metal was prepared in 1910 by
Matthew Hunter, who heated titanium (IV) chloride together with sodium in a steel bomb. Titanium is named after the Titans, the sons of the Earth goddess in Greek mythology.
Characteristics:
Pure titanium is a light, silvery-white, hard, lustrous metal. It has excellent strength and corrosion resistance.
At high temperatures the metal will burn in air and, unusually, titanium will also burn in pure nitrogen. Titanium is ductile and it is malleable when heated.
Uses:
Titanium met is used as an alloying agent with metals including aluminum, iron, molybdenum and manganese.
Alloys of titanium are mainly used in aerospace, aircraft and engines where strong, lightweight, temperature-resistant materials are needed. As it is resistant to seawater, titanium is used for hulls of ships, propeller shafts and other structures exposed to the sea. Titanium is also used in joint replacement implants, such as the ball-and-socket hip joint. Titanium is used in several everyday products such as drill bits, bicycles, golf clubs, watches and laptop computers.
