About Aluminum Nitride AlN powder
Similar to other semiconductors. aluminum nitride The powder is a great material to use for creating sintered bodies. It has high thermal conductivity, excellent electrical insulation, and good thermal expansion.
Aluminum nitride can withstand high temperatures and melts at around 2200degC in an inert environment. AlN can be decomposed in vacuum at about 1800°C. The temperature at which surface oxidation occurs in air is 700°C. At room temperature, an oxide layer on the surface of the material with thicknesses between 5-10 nanometers has been observed. This oxide layer is capable of protecting the material up to 1370 degC. At higher temperatures, bulk oxidation takes place. Aluminum nitride remains stable up to 980degC in carbon dioxide and hydrogen atmospheres.
The aluminum nitride cte It is lower than that for alumina oxide or beryllium oxide, and has a coefficient of thermal extension of 4.5*10-6/degC.
It slowly dissolves through grain boundary erosion in inorganic and strong acids. The aluminum nitride particles then erode to dissolve the material in alkali. Aluminum nitride can withstand most molten salts, including chloride and cryolite.

Application AlN powder

Aln aluminium nitride a non-metallic inorganic material with a diamond-like nitride and high thermal conductivity is an excellent thermal conductivity. It also has a low coefficient for thermal expansion. This is an excellent thermal shock material. This crucible metal is ideal for melting aluminum and pure iron. It has a high resistance to molten-metal corrosion. Aluminium nitride can also be used as an electrical insulation with excellent dielectric properties. It also offers good potential for use in the manufacturing of electrical components.
1. Manufacture the integrated circuit foundation plate for the electronic device, optical device and radiator.
2. Thermoconductive silicon and thermoconductive epoxy resin.
3. A nano-lubricant, antiwear agent.
4. Thermoconductive high-temperature plastic
An epitaxially-grown thin-film of crystalline aluminum Nitride (SAWs), is used because AlN has piezoelectric characteristics. A thin-film bulk Acoustic Resonator (FBAR) is one example of an RF filter that is widely used in mobile phones. MEMS devices that use aluminum nitride between two layers of metal are this type.
AlN can also serve as a material for piezoelectric, micromachined ultrasound transmitters. They emit and receive an ultrasonic signal and can be used for indoor rangefinding up to 1 meter.

Electrical equipment can use Aluminium nitride-ceramic . The aluminum nitride glaze ceramics are resistant to most molten metals such as aluminum, copper and lithium.
The aluminum nitride sheets can be used for power modules, IGBT, MOSFET, or LED packages.
