What is aluminum nitride powder? Aluminum nitride is a new type of ceramic material with excellent comprehensive performance. Aluminum nitride ceramic powder has 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, packaging material for high-power rectifier components, 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, Evaporating dish, ceramic tool, cutting tool, microwave dielectric material, used to synthesize high-quality LED phosphor.
Use of aluminum nitride powder Nano aluminum nitride is used in crucibles, evaporation boats, protection tubes of thermocouples, high-temperature insulating parts, microwave dielectric materials, high-temperature and corrosion-resistant structural ceramics and transparent aluminum nitride microwave ceramic products for smelting non-ferrous metals and semiconductor materials gallium arsenide, as well as in PI resin, heat-conducting insulating mica tape, heat-conducting grease, insulating paint, and heat-conducting oil.
Chemical properties of aluminum nitride powder The room temperature strength is high, and the strength decreases slowly with the increase in temperature. Aluminum nitride has good thermal conductivity, a low thermal expansion coefficient and is a good thermal shock-resistant material. It has excellent thermal shock resistance. The thermal conductivity of AlN is 2-3 times that of Al2O3, and the strength is higher than that of Al2O3 during hot pressing. Aluminum nitride has good corrosion resistance to Al and other molten metals, gallium arsenide, etc., especially for molten Al liquid; it also has excellent electrical insulation and dielectric properties. However, aluminum nitride has poor oxidation resistance at high temperatures. It is easy to absorb moisture in the atmosphere, and contact wet air, water, or aqueous liquid to generate heat and nitrogen and decompose rapidly. When decomposed at 2516 ℃, the thermal hardness is very high, and it does not soften and deform even before the decomposition temperature. Aluminum nitride and water can react slowly at room temperature. It reacts with dry oxygen at above 800 ℃.
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.
