What is Aluminum Nitride

What is Aluminum Nitride?

Known for its high energy conductivity and electrically insulating features, it makes an ideal material to make semiconductors. In the field of light emitter technology, it can also be utilized as a heat sink.

Eigenschaften of Aluminum Nitride

Aluminum nitride is an organic compound consisting of nitrogen as well as aluminum. It belongs to the wurtzite crystal type and has a bandgap value of 6 eV at temperatures of room temperature. This makes it ideal for use in the field of optoelectronics with deep ultraviolet. It also functions in the form of a circuit bus in semiconductors.

Aluminum Nitride (Al) is a technical ceramic that is available in thin and thick varieties. It is manufactured using a carbothermal reduction process. However, this process can be expensive, so an easier process to prepare the powder has to be investigated. Sintering aids of various kinds were employed to increase the strength of the material within specifications.

Affectation of Aluminum Ntride

Aluminum nitride may be used to create optical substances such as nanotubes to make chemical sensors. It can also be used as a substrate material for silicon processing. It is highly resistant erosion, corrosion and molten metals. It is stable at elevated temperatures, even in an inert air.

Aluminum nitride is found in virtually every metal. It can be found in a gray-blue, white or gray powder. It's easily soluble when mixed with water and inorganic acids. However, it's unstable in hydrogen atmospheres. It's also extremely flammable.

It is employed for mobile phones, to create wireless frequency filters. It is also employed in robotics and medical imaging. The piezoelectric properties it has are utilized in bulk acoustic thin-film Resonators.

There is a report that the majority of current research focuses on the development of semiconductor (GaN or AlGaN) LEDs that operate in the ultraviolet, where the wavelength of light is 250 nm. In May 2006, it was discovered that a diode that was inefficient could emit light with about 210 nanometers in wavelength. A single crystal of aluminum nitride can have an energy gap as high as 6.2eV that is determined by vacuum ultraviolet reflectance. Theoretically it is believed that the energy gap permits certain waves with wavelengths in the range of 200 nanometers to traverse through. However, for it to be implemented commercially, many difficulties need to be solved. Aluminum nitride can be found in optoelectronic engineering, including inductive layers in optical storage interfaces and electronics, semiconductors that have high thermal conductivity, as well as military applications.

Epitaxial stretching of AlN crystals is also used in surface acoustic-wave detectors due to the characteristics of the AlN piezoelectric effects. The detectors are put onto the silicon substrate. Only a handful of places can effectively make these thin films.

The aluminum nitride materials have a high strength at room temperatures and high temperatures, with a low expansion coefficient, as well as good thermal conductivity, and can be utilized as heat exchangers on structures with high temperatures.

Utilizing the resistance to corrosion of aluminum, iron and various alloys the aluminum nitride and other ceramics can be utilized as crucibles or casting molds to smelt Al, Cu, Ag Pb, Pb and other metals.
