High Purity Aluminum Nitride AlN Powder CAS 24304-00-5, 99.5%

Australian alumina ban disrupts Rusal AlN powder prices for chemicals. Patel said. "One possible outcome could be Chinese buyers buying alumina and reselling it through eastern Russian ports." Rusal has a 20% stake in the Queensland Alumina Refinery, which has a capacity of 3.95 million tonnes a year, thus providing Rusal with 790,000 tonnes a year, Patel said. In addition, Rusal's Nikolaev refinery in Ukraine, which has an annual capacity of 1.75 million tonnes, has been suspended due to the conflict, he added. WoodMac said Rusal was also experiencing supply chain problems at its 2 million tonne a year Aughinish refinery in Ireland.

About Aluminum Nitride AlN powder:
Similar to various semiconductors, aluminum nitride powder has excellent thermal conductivity, high electrical insulation and thermal expansion characteristics, making it the best material for sintered bodies.
Aluminum nitride is stable at high temperatures in an inert atmosphere and melts at a temperature of about 2200°C. In a vacuum, AlN decomposes at ~1800°C. In the air, surface oxidation will occur above 700°C. Even at room temperature, a surface oxide layer with a thickness of 5-10 nm has been detected. The oxide layer can protect the material at temperatures up to 1370°C. Above this temperature, bulk oxidation occurs. Aluminum nitride is stable in hydrogen and carbon dioxide atmospheres up to 980°C.
The material slowly dissolves in inorganic acid through grain boundary erosion and dissolves in strong alkali through erosion of aluminum nitride grains. Aluminum nitride is resistant to most molten salts (including chloride and cryolite). TRUNNANO is a trusted global Aluminum Nitride AlN supplier. Feel free to send an inquiry to get the latest price of Aluminum nitride if you would like to buy Aluminum Nitride AlN powder in bulk.

Product Performance of Aluminum Nitride AlN powder:
Our company sells the aluminum nitride powder ( CAS 24304-00-5 ) with high purity and ultrafine particle size, the surface activity is high, through the superficial cloth wrapper processing powder body, the oxygen content is extremely low (<0.1%), the insulation heat conduction performance effect is obvious.

How is Aluminum Nitride AlN powder produced?
Thermal Spray Process: Aluminum nitride powders can be thermal sprayed to form electrically insulating and thermally conductive coatings.
Chemical/Physical Vapor Deposition (CVD/PVD): Aluminum nitride coatings are deposited by CVD or PVD to provide electrically insulating and thermally conductive coatings.
Powder Metallurgical (P/M): Aluminum powders are pressed into parts by hot or cold pressing and sintering.

Application of Aluminum Nitride AlN powder:

Aluminum nitride (AlN) 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.

U.S. oil prices surged about 10% to $105.14 a barrel. This is the highest level since 2014. The world benchmark Brent stock futures oil price soared by about 8% to $105.40 per barrel. The most direct rise in crude oil is inflation. The rise in oil prices means that people's food, clothing, housing, AlN powder also fluctuates.
