Al nitride
Aluminium nitride (AlN) is a solid nitride of aluminium. It has a high thermal conductivity of up to 321 W/(m·K) and is an electrical insulator. Its wurtzite phase (w-AlN) has a band gap of ~6 eV at room temperature and has a potential application in optoelectronics operating at deep ultraviolet frequencies. See more AlN was first synthesized in 1862 by F. Briegleb and A. Geuther. AlN, in the pure (undoped) state has an electrical conductivity of 10 –10 Ω ⋅cm , rising to 10 –10 Ω ⋅cm when doped. Electrical breakdown occurs … See more AlN is synthesized by the carbothermal reduction of aluminium oxide in the presence of gaseous nitrogen or ammonia or by direct nitridation of aluminium. The use of sintering aids, such as Y2O3 or CaO, and hot pressing is required to produce a dense technical … See more • Boron nitride • Aluminium phosphide • Indium nitride • Aluminium oxynitride • Titanium aluminium nitride, TiAlN or AlTiN See more Aluminium nitride is stable at high temperatures in inert atmospheres and melts at about 2200 °C.
