Titanium Martina Tycová Tereza Mlatečková
2
Discovery of titanium was discovered by William Gregor in 1791 first was named by Martin Klaprothem in 1795 is never found in elemental form (only in alloys and compounds)
3
Occurrence Titanium is seventh most widespread metal in earth crust. Titanium is included in minerals. ilmenit FeTiO 3 rutil TiO 2 widespread – rozšířený crust - kůra
4
ilmenit FeTiO 3 crystal structures perowskit CaTiO 3 rutil TiO 2
5
Properties hard, light, tenacious, resistent to extremes of temperature, corrosion and salt water soluble in concentrate acids and insoluble in water extremely brittle, malleable, ductile strong as steel, but lighter; twice strong than aluminium tenacious – houževnatý malleable – kujný ductile – tažný brittle - křehký NameTitanium SymbolTi Atomic number22 Atomic mass47,867 Melting point1660°C Boiling point3287°C Crystal structurehexagonal Colorsilverish
6
Industrial production TiCl 4 + 2Mg -> Ti + 2MgCl 2 Compounds TiO 2 - known as titanium white - used for white covering pigment TiCl 4 –interproduct of manufacture of elementary titanium
7
Usage for alloys – aluminium, molybdenon, manganese, iron and other metals solar observatories paint as excellent reflector of infrared radiation missiles, space capsules (=Apollo) aircraft – components, engines, fire walls, outer skin, airframes missile – řízená střela engine – motor airframe – kostra letadla capsule – kabina
8
surgery - replacement for joints, bone and cartilage - pipe and tank lining in food processing - teeth replacement - náhrada cartilage - chrupavka joints - klouby tank lining – vložka do žaludku
