Aluminum Nitride powder AlN
Many semiconductors have similar properties.
The powder is the best material to use for sintered bodies because of its excellent thermal conductivity.
Aluminum nitride remains stable in an inert gas atmosphere at high temperature and melts around 2200degC. AlN breaks down in a vacuum around 1800degC. In the atmosphere, surface oxidation is observed above 700degC. At room temperature, an oxide surface layer has been detected with a 5-10nm thickness. The oxide film can protect the material even at temperatures as high as 1370degC. Above this temperature, the bulk oxidation process occurs. Aluminum nitride can be stable in hydrogen or carbon dioxide atmospheres as high as 980degC.
It is important to note that the word "you" means "you".

Application of Aluminum Nitride AlN powder:
Aln aluminum nitride is an inorganic non-metallic material of diamond-like nitride with good thermal conductivity and a low coefficient of thermal expansion. It is a good thermal shock material. Strong resistance to molten metal corrosion, it is an ideal crucible material for melting and casting pure iron, aluminum or aluminum alloy. Aluminum nitride is also an electrical insulator with good dielectric properties, and it also has good application prospects in the field of electrical component manufacturing.
1. Manufacture integrated circuit foundation plate, the electronic device, the optical device, the radiator, the high-temperature crucible prepares metal-based and the high score subbasis compound materials
2. Heat conducting silicon and thermally conductive epoxy resin.
3. Nano lubricant and antiwear agent.
4. High thermal conductive plastic
Epitaxially grown thin-film crystalline aluminum nitride is used for surface acoustic wave sensors (SAWs) deposited on silicon wafers because of AlN's piezoelectric properties. One application is an RF filter, widely used in mobile phones, which is called a thin-film bulk acoustic resonator (FBAR). This is a MEMS device that uses aluminum nitride sandwiched between two metal layers.
AlN is also used to build piezoelectric micromachined ultrasound transducers, which emit and receive an ultrasound and which can be used for in-air rangefinding over distances of up to a meter.
Aluminum nitride ceramic is used in various electrical equipment. In addition to the coefficient of thermal expansion and electrical insulation, aluminum nitride ceramics can resist the erosion of most molten metals, such as copper, lithium and aluminum.
Aluminum nitride substrates have high thermal conductivity and insulation, and can be used in power modules (MOSFET, IGBT), LED packages and modules for cooling and protection circuits.
