Product Description Detailed Photos Aluminum Nitride, AIN Ceramic PropertiesAluminum Nitride, formula AlN, is a newer material in the technical ceramics family. While its discovery occurred over 100 years ago, it has been developed into a commercially viable product with controlled and reproducible properties within the last 20 years..Key Aluminum Nitride Properties Good dielectric properties High thermal conductivity Low thermal expansion coefficient, close to that of Silicon Non-reactive with normal semiconductor process chemicals and gases.Typical Aluminum Nitride Uses Substrates for electronic packages Heat sinks IC packages Power transistor bases Microwave device packages Material processing kiln furniture Semiconductor processing chamber fixtures and insulators Molten metal handling componentsGeneral Aluminum Nitride InformationAluminum nitride has a hexagonal crystal structure and is a covalent bonded material. The use of sintering aids and hot pressing is required to produce a dense technical grade material. The material is stable to very high temperatures in inert atmospheres. In air, surface oxidation begins above 700°C. A layer of aluminum oxide forms which protects the material 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 dissolves slowly in mineral acids through grain boundary attack, and in strong alkalis through attack on the aluminum nitride grains. The material hydrolyzes slowly in water. Most current applications are in the electronics area where heat removal is important. This material is of interest as a non-toxic alternative to beryllia. Metallization methods are available to allow AlN to be used in place of alumina and BeO for many electronic applications.Hebei Suoyi New Material Technology Co., Ltd. was formally established in 2014 and is located in Handan, a 3000-year-old ancient city in China.The company has several branch factories, located in Shandong, Henan, Shanxi and so on. There are 268 professionals in the headquarters of the company,and more than 1,000 employees in each factory. Compared with other companies, we have a more mature supply chain, professional team, preferential prices, etc.,and the repurchase rate of cooperative customers is as high as 70%, so that you can rest assured to buy Suoyi products.
