What is Aluminum Nitride

What is Aluminum Nitride?

Famous for its superior energy conductivity and electrically insulating capabilities, aluminum Nitride makes an excellent material to create semiconductors. In light emitter lighting technology, it's utilized as a heat sink.

Properties of Aluminum Nitride

Aluminum nitride is an inorganic substance composed of nitrogen and aluminum. It belongs to the wurtzite crystal and has a bandgap of 6. eV at the temperature of ambient. This makes it ideal for applications in the field of deep-UV optoelectronics. It can also be used on circuit cards in semiconductors.

Aluminum Nitride can be described as a dense technical ceramic material available in thin and thick versions. It is produced by an acid reduction process. But, this process could be expensive, so there is a more economical method for powder preparation that is required to be researched. Several sintering aids were also used to bring the amount of material to specifications.

Application of Aluminum Nitride

Aluminum nitride is a good choice to make optical material such as nanotubes to make chemical sensors. It can also be used an element of the silicon processing. It is highly resistant erosion, corrosion and molten metals. It's stable in high temperatures under an inert gas atmosphere.

Aluminum nitride can be found in almost any metal. It is a grey-blue or white powder. It is soluble in water and inorganic acids. However, it's unstable in hydrogen atmospheres. Also, it is highly flammable.

It is employed by mobile phone manufacturers to create radiation frequency filters. It is also used in medical imaging and robotics. These properties are utilized in bulk thin-film acoustic resonators.

It was reported that most of the current research focuses on the creation of semiconductor (GaN or AlGaN) LEDs that operate in the wavelength of the ultraviolet which means that the wavelength of light is 250 nanometers. In May 2006 it was discovered that an inefficient dimer could emit light with about 210 nanometers in wavelength. A single crystal of aluminum nitride includes an energy gap that is 6.2eV as measured by ultraviolet vacuum reflectance. Theoretically the gap allows some waves with wavelengths in the vicinity of 200 nanometers to be able to pass through. However, when it is implemented commercially it will require a lot of hurdles to be resolved. Aluminum Nitride is used in optoelectronic technology, including inductive layers for optical storage interfaces as well as electronic substrates. It is also used in chip carriers, electronic components that have excellent thermal conductivity and military applications.

Epitaxial stretching of AlN crystals is also employed for surface acoustic wave detectors because of the properties associated with the AlN piezoelectric effect. The detectors sit on the silicon wafer. Only a handful of locations are able to reliably make these thin films.

Aluminum nitride ceramics are strong in toughness at room temperature and high temperatures, with a low expansion coefficient, as well as good thermal conductivity, and can be utilized as heat exchanger materials for structure parts that operate at high temperatures.

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