Application of aluminum nitride AIN

Overview of Aluminum Nitride AIN

Aluminum nitride, covalent bond compound, chemical formula is AIN, is atomic crystal, belongs to diamond-like nitride, hexagonal crystal system, wurtzite crystal structure, non-toxic, white or off-white

Aluminum nitride, a covalent bond compound, is an atomic crystal, belonging to diamond-like nitride, hexagonal crystal system, wurtzite type crystal structure, non-toxic, white or off-white.

Aluminum nitride AlN can be stabilized up to 2200℃. The room temperature strength is high, and the strength decreases slowly with the increase of temperature. It has good thermal conductivity and small coefficient of thermal expansion, making it a good thermal shock resistance material. It has strong resistance to molten metal corrosion and is an ideal crucible material for melting and casting pure iron, aluminum or aluminum alloy. Aluminum nitride is also an electrical insulator with good dielectric properties, and it is also very promising for electrical components. The aluminum nitride coating on the surface of gallium arsenide can protect it from ion implantation during annealing. Aluminum nitride is also a catalyst for the transformation from hexagonal boron nitride to cubic boron nitride. It reacts slowly with water at room temperature. It can be synthesized from aluminum powder at 800~1000℃ in ammonia or nitrogen atmosphere. The product is white to gray-blue powder. Or synthesized by Al2O3-C-N2 system at 1600~1750℃, the product is off-white powder. Or aluminum chloride and ammonia are made by gas phase reaction. The coating can be synthesized by vapor deposition method in AlCl3-NH3 system.

Aluminum nitride AIN application

The report pointed out that most of the current research is developing a semiconductor (gallium nitride or alloy aluminum gallium nitride) based light-emitting diode that operates in ultraviolet light, and the wavelength of light is 250 nanometers. There was a report in May 2006 that an inefficient diode can emit light waves with a wavelength of 210 nanometers. Measured by vacuum ultraviolet reflectance, a single aluminum nitride crystal has an energy gap of 6.2 eV. In theory, the energy gap allows some waves with a wavelength of about 200 nanometers to pass. However, many difficulties need to be overcome when it is implemented commercially. Aluminum nitride is used in optoelectronic engineering, including as dielectric layer in optical storage interface and electronic substrate, as chip carrier with high thermal conductivity, and for military use.

Due to the characteristics of the piezoelectric effect of aluminum nitride, the epitaxial stretching of aluminum nitride crystals is also used in surface acoustic wave detectors. The detector will be placed on the silicon wafer. There are very few places where these thin films can be reliably manufactured.

The use of aluminum nitride ceramics has high room temperature and high temperature strength, small expansion coefficient, and good thermal conductivity. It can be used as a heat exchanger material for high-temperature structural parts.

Using aluminum nitride ceramics can withstand the corrosion properties of iron, aluminum and other metals and alloys, it can be used as a crucible and casting mold material for melting metals such as Al, Cu, Ag, and Pb.
