What is aluminum nitride powder? Aluminum nitridehas good thermal conductivity, thermal expansion coefficient matching with silicon and gallium arsenide, electrical insulation, high melting point, and good optical transmission performance. Its main uses are a ceramic substrate for large-scale integrated circuits, thermal conductive filler for thermal conductive paste, thermally conductive silicone grease, thermal conductive filler for other heat dissipation materials, high-temperature lubricant, and crucible-making.
Use of aluminum nitride powder Application of aluminum nitride powder in high thermal conductivity silicone rubber: aluminum nitride powder has a good matching performance with silicon and is easy to disperse in rubber. It can greatly improve silicone rubber's thermal conductivity without affecting the rubber's mechanical properties. During the addition process, unlike oxides, the viscosity increases rapidly, and the addition amount is very small (according to the thermal conductivity requirements, it can generally increase the thermal conductivity by 50% - 70% by about 5%). It is widely used in military, aviation, and information engineering.
Preparation of aluminum nitride powder The carbothermal reduction method of aluminum oxide: Al203+3C+N2 → 2AlN+3CO This method is currently widely used in industrial production, and its research is relatively in-depth. In this method, calcium oxide, calcium fluoride, yttrium oxide, etc., are often added as catalysts in the preparation of aluminum nitride powder, in which calcium fluoride is more effective in reducing the activation energy and improving the reaction rate. The aluminum nitride powder prepared by this method has high purity and good forming and sintering properties but a high synthesis temperature and long reaction time; the powder size is large.
Price of aluminum nitride powder Aluminum nitride powder particle size and purity will affect the product's price, and the purchase volume can also affect the cost of aluminum nitride powder. A large amount of large amount will be lower. The price of aluminum nitride powder can be found on our company's official website.
