Aluminium nitride (Al N) is a solid nitride of aluminium. It has a high thermal conductivity of up to 321 W/(m·K) [ 5 ] 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.
Four pnictides, aluminium nitride (AlN), aluminium phosphide (AlP), aluminium arsenide (AlAs), and aluminium antimonide (AlSb), are known. They are all III-V semiconductors isoelectronic to silicon and germanium, all of which but AlN have the zinc blende structure. All four can be made by high-temperature (and possibly high-pressure) direct ...
More conveniently, the salt can be made by reacting nitric acid with aluminium hydroxide. Aluminium nitrate may also be prepared a metathesis reaction between aluminium sulfate and a nitrate salt with a suitable cation such as barium, strontium, calcium, silver, or lead. e.g. Al 2 (SO 4) 3 + 3 Ba(NO 3) 2 → 2 Al(NO 3) 3 + 3 BaSO 4.

Aluminium oxynitride (marketed under the name ALON by Surmet Corporation [3]) is a transparent ceramic composed of aluminium, oxygen and nitrogen. Aluminium oxynitride is optically transparent (≥80% for 2 mm thickness) in the near-ultraviolet , visible, and mid-wave- infrared regions of the electromagnetic spectrum.

Aluminium (or aluminum in North American English) is a chemical element; it has symbol Al and atomic number 13. Aluminium has a density lower than that of other common metals, about one-third that of steel. It has a great affinity towards oxygen, forming a protective layer of oxide on the surface when exposed to air.
