Anwendungen & Verwendung
Verwenden
Aluminum nitride possesses very high thermal conductivity and effectively used in the ceramic industry. It finds application in deep ultraviolet optoelectronics, steel production, dielectric layers in optical storage media, chip carriers and as a crucible to grow crystals of gallium arsenide. It is also used as a radio frequency filter, which finds application in mobile phones. Further, it is used as a circuit carrier in semiconductors. In addition to this, it is used as a heat-sink in light-emitting diode lighting technology.
Herstellung & Synthese
synthetische
Aluminum nitride is conveniently prepared by an electric arc between aluminum electrodes in a nitrogen atmosphere. Crucibles of the pressed powder, sintered at 1985°C, are resistant to liquid aluminum at 1985°C, to liquid gallium at 1316°C, and to liquid boron oxide at 1093°C. Aluminum nitride has good thermal shock resistance and is only slowly oxidized in air (1.3% converted to Al2O3 in 30 h at 1427°C). It is inert to hydrogen at 1705°C but is attacked by chlorine at 593°C.
