What is Aluminum Nitride

What is Aluminum Nitride?

Known for its high conductivity in thermal and electrical properties, aluminum nitride is an excellent material to create semiconductors. In the field of light emitter technology, it's employed as a heater.

Qualities of the Aluminum Nitride

The inorganic aluminum nitride substance composed of nitrogen and aluminum. It belongs to the wurtzite-wurtzite Crystal Structure and has a bandgap of 6 eV at room temperature. This makes it suitable for applications in the optics of deep ultraviolet. It is also utilized to act as a carrier for circuits semiconductors.

Aluminum Nitride is a dense technical ceramic material which is available in thin and thick versions. It is made by the process of carbothermal reduction. However, this method can be costly, therefore there is a more economical method for powder preparation that is required to be researched. Several sintering aids were also used to raise the density of the material up to specifications.

Utilization of the Aluminum Nitride

Aluminum nitride could be used in the manufacture of optical materials such as nanotubes for chemical sensors. It is also used as the substrate material for silicon processing. It is extremely resistant corrosion, oxidation and even molten metals. It's stable even at higher temperatures with an inert atmospheric.

Aluminum nitride can be found in virtually every metal. It is a gray-white to white powder. It's insoluble in water and inorganic acids. But, it's unstable in hydrogen atmospheres. Also, it is highly flammable.

It is employed within mobile phones in order to form radio frequency filters. It is also used in robotics and medical imaging. Its piezoelectric property is also utilized in bulk thin-film acoustic Resonators.

It was reported that the bulk of recent research is focused around the creation of semiconductor (GaN or AlGaN) built LEDs that operate in the UV, which means that the wavelength of light is 250 nm. In May 2006 it was discovered that a diode that was inefficient could emit light with around 210 nanometers. A single aluminum nitride crystal with an energy gap of 6.2eV calculated by the vacuum ultraviolet reflectance. Theoretically, the gap lets certain waves that have wavelengths in the range of 200 nanometers to pass through. However, when you implement it commercially in the market, many obstacles need to be resolved. Aluminum nitride can be found in optoelectronics, for example, inductive layers used in optical storage interfaces, electronic substrates, chip carriers with high thermal conductivity, and military applications.

Stretching epitaxially of AlN crystals can also be used in surface acoustic waves detectors because of the properties of the AlN piezoelectric force. The detectors are placed upon the silicon wafer. Only a handful of places can consistently produce these thin films.

Ceramics made of aluminum nitride have high resistance to temperature changes and high temperature, a small expansion coefficient, and a high thermal conductivity, and can be utilized as heat exchangers materials for the construction of high-temperature structures.

Utilizing the resistance to corrosion of iron, aluminum, and various alloys Aluminum nitride ceramics may serve as crucibles as casting mold materials to smelt Al, Cu, Ag or Pb as well as other metals.
