Aluminum Nitride (AlN) Ceramic Crucible has good electrical insulation and resistivity, which is an ideal material for use in thermal management and electrical applications. It can withstand temperatures of around 1300°C in air without experiencing overall oxidation, although this process begins after 700°C. In a vacuum, AlN decomposes at 1800°C. AlN melts at 2200°C, with protection from an inert atmosphere. Generally, the operating temperatures for AlN products are 800°C in air, 1700°C in a vacuum, and 2100°C in an inert atmosphere.
