What is Aluminum Nitride?
Awarded for its outstanding conductivity in thermal and electrical property, aluminium nitride makes an excellent material for making semiconductors. In light emitter lighting technology, it's also employed as a heater.
The properties of aluminum nitride
Aluminum nitride , an inorganic substance composed of nitrogen and aluminum. It belongs to the wurtzite crystal structure and has a bandgap of 6 eV at room temperature. This makes it suitable for use in the field of deep-UV optoelectronics. It also functions as an electronic circuit carrier in semiconductors.
Aluminum Nitride, a very dense technical ceramic material , available in thick and thin forms. It is manufactured using a carbothermal reduction process. However, this process may cost a lot of money, so an alternative process for preparation of powder that is less expensive needs to be investigated. Sintering aids of various kinds were used to bring the density of the powder to specifications.
Utilization of the Aluminum Nitride
Aluminum nitride can be used to make optical material such as nanotubes used in chemical sensors. It is also used as an element of the silicon processing. It is highly resistant to corrosion, oxidation, and molten metals. It's stable at high temperatures and in an inert environment.
Aluminum nitride can be found in almost all metals. It is a gray or white powder. It's soluble in water as well as inorganic acids. It is, however, unstable in hydrogen atmospheres. It is also highly flammable.
It is used with mobile phones to form the radio frequency filter. It is also utilized in robotics and medical imaging. The piezoelectric properties of the material are employed in thin-film bulk acoustic resonators.
There is a report that most of the current research focuses on the creation of semiconductor (GaN or AlGaN) based LEDs that operate in the wavelength of the ultraviolet where the wavelength of light is 250 nanometers. In May 2006 it was discovered that an inefficient diode can emit light with an nm wavelength of 210. A single crystal of aluminum nitride features an energy-gap of 6.2eV as measured by ultraviolet vacuum reflectance. Theoretically the gap lets certain waves that have lengths of 200 nanometers to travel through. However, when using it commercially it will require a lot of hurdles to be resolved. The aluminum nitride compound is employed in optoelectronics engineering, such as Inductive layers on optical storage interfaces, electronic chips, substrates for chip drivers that have high thermal conductivity, as well as military applications.
It is known that epitaxial stretching in AlN crystals is also used in surface acoustic-wave detectors because of the properties characteristic of the AlN piezoelectric phenomenon. The detectors sit on the silicon wafer. Only a handful of places can safely make these films.
Aluminum nitride-based ceramics possess high strength at room temperature and high temperatures, and a very low expansion coefficient, as well as good thermal conductivity. They can be used as heat exchanger materials for high-temperature structural components.
Utilizing the resistance to corrosion of aluminum, iron and alloys of other metals Aluminum nitride ceramics may be used as crucibles as well as casting molds to smelt Al, Cu, Ag Pb, Pb and other metals.
