What is aluminum nitride powder? Aluminum nitride (AlN) is a kind of inorganic non-metallic material of diamond nitride, with good thermal conductivity and a low coefficient of thermal expansion. It is a good heat-resistant impact material. It has strong resistance to molten metal erosion and 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. It also has a good application prospect in electrical component manufacturing. Ultrafine aluminum nitride powder is widely used in large-scale integrated circuit production.
Use of aluminum nitride powder It is used to manufacture thermal conductive silica gel and thermally conductive epoxy resin. Ultra-high thermal conductive nano-aluminum nitride composite silica gel has good thermal conductivity, good electrical insulation, wide electrical insulation service temperature (operating temperature - 60 ℃ - 200 ℃), low consistency, and good construction performance. It is widely used in the gap filling of CPU and radiator, high-power triode, silicon controlled element, diode, and heat transfer medium at the thin seam in contact with the substrate.
Preparation of aluminum nitride powder Direct nitriding method: nitrogen and aluminum are directly nitrided, crushed, and graded. The quality of aluminum nitride products is affected by the reaction furnace temperature, the premixing of raw materials, the mixing proportion of recycled aluminum nitride powder, and the specific surface area of aluminum nitride. Therefore, it is necessary to strictly control the process to obtain stable aluminum nitride powder (such as specific surface area, primary particle size, agglomerated particle size, bulk density, and surface characteristics).
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.
