The element Titanium By: Teona Studemire
Titanium • Name: Titanium • Symbol: Ti • Type: Transition Metal • Atomic mass: 47.88 • Melting point: 1941 K (1668 oC) • Boiling point: 3560 K (3287 oC) • Atomic number:22 • Worth: 18 dollars a pound • 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. • Information received from-http://www.chemicool.com/elements/titanium.html
Uses of Titanium • Since it is resistant to seawater, titanium is used for the 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.
Natural titanium Form and whereabouts. Man- made form • Titanium is the ninth most abundant metal in the Earth's crust. Titanium is not found freely in nature but is found in minerals such as rutile (titanium oxide), ilmenite (iron titanium oxide) and sphene (titanite or calcium titanium silicate). Commercially, the metal is isolated using the Kroll process which initially prepares titanium oxide from the mineral ilmenite. The oxide TiO2 is then converted to the chloride ( TiCl4) through carbochlorination. This is condensed and purified by fractional distillation and then reduced with molten magnesium in an argon atmosphere. • Titanium is also man- made Natural form
Compounds of Titanium • Oxide(s): TiO, Ti2O3, TiO2 (titania) + more • Chloride(s): TiCl2, TiCl3, TiCl4 • Hydride(s): TiH2
Physical Properties and state of matter • State (s, l, g): solid • Melting point: 1941 K (1668 oC) • Boiling point: 3560 K (3287 oC) • Density @ 293 K: 4.50 g/cm3 • Specific heat capacity: 0.52 J g-1 K-1 • Heat of atomization: 471 kJ mol-1 • Heat of fusion: 14.15 kJ mol-1 • Heat of vaporization: 425 kJ mol-1
Chemical properties • Reaction with air: mild • Titanium metal is considered to be non-toxic. As metal shavings, or powder, it is a considerable fire hazard. Titanium chlorides are corrosive.
