Aluminum nitride (also known as atomic crystal) is a white or off-white powder.
What property does aluminum nitride have?
AlN has a stabilizing range of up to 2200. The strength at room temperatures is very high and increases and decreases gradually with temperature. Aluminum nitride, with its low thermal expansion and good thermal conductivity, is an excellent material for thermal shock. It is resistant against molten corrosion, and it’s an ideal material for casting pure aluminum, iron or aluminum alloy.
Aluminum nitride also has excellent dielectric properties. It is also promising for use as an electrical component. Aluminum nitride can be applied to the surface of gallium-arsenide in order to protect it against ion implantation during annealing. Aluminum nitride also acts as a catalyst for the transformation of hexagonal boron to cubic boron.
What are the applications of aluminum nitride?
Aluminum nitride has many uses in optoelectronics. It is used as a dielectric in optical storage interfaces and electronic substrates, as a chip carrier that has high thermal conductivity for military purposes, and also as a chip carrier.
A surface acoustic detector also uses epitaxial stretching due to the piezoelectric effects of aluminum. The detector sits on a silicon chip, but there are only a handful of places that can produce these thin films reliably.
Aluminium nitride is a ceramic material with a low expansion coefficient, good thermal conductivity, and high strength in high temperatures. It can also be used to make heat exchangers for structural components that are exposed to high temperatures.
The aluminum nitride can resist the corrosion of metals, alloys, and iron, and it can also be used to melt metals, such as Al. Cu. Ag. Pb.
