How do you define it?

Aluminum Nitride

The covalent bond chemical, aluminum nitride or AIN is an atomic compound that is not toxic, safe, white, or off-white.

Aluminum Nitride has the following main attributes

AlN remains stable at 2200degC. Strength at room temperatures is good, but it decreases gradually with temperature. It is an excellent thermal shock material because it has a low thermal expansion coefficient and good thermal conductivity. Aluminum nitride is resistant to corrosion and is a good crucible for the casting of pure iron or aluminum. The potential electrical component aluminum nitride, which is an excellent electrical insulator that has good dielectric characteristics and also offers promising results as an electrical component, is aluminum nitride. An aluminum nitride layer on gallium arsenide protects it against ion implantation in annealing. Aluminium nitride also acts as a catalyst in the transformation of hexagonal to cubic boron nutride. It is slow to react with water at room temperatures. Aluminum powder can be made in nitrogen atmosphere or ammonia at 8001000. It is white to gray-blue and easily synthesized. It can be produced by reaction of Al2O3C–N2 system at 16001750. The powder is off-white. Oder prepared using vapor-phase reactions of aluminum chloride, ammonia. It can be prepared using the AlCl3-NH3 vapor-phase method.

The Use of Aluminum Niitride

The majority of current research is focused upon developing a semiconductor light-emitting diode, either gallium nitride (or alloy aluminum galium nitride), that emits ultraviolet light having a wavelength of 250 nanometers. An inefficient diode could emit light up to 210nm (as reported by 1 May 2006). An aluminum nitride single crystal has an energy gap measuring by reflectance from ultraviolet rays. It has a value of 6.2eV. According to theory, this energy gap permits waves at wavelengths of around 200 nanometers to pass through. However, commercialization presents many problems. Optoelectronic engineering uses aluminum nitride as an optical layer, in electronic substrates and in chip carriers. Military applications also use it.

The properties of aluminum Nitride’s piezoelectric effects make epitaxial stretching crystals of aluminum Nitride possible for use in surface acoustic-wave detectors. They are mounted on silicon wafers. It is difficult to produce thin films reliably in these locations.

Aluminum nitride clays can be used for heat exchangers and parts that require high temperatures.

It can be used in crucibles or casting materials to smelt Al, Cu, Ag and Pb by using aluminum nitride clays. This ceramic resists the corrosion properties iron, aluminum, and other metals.
