Aluminum nitride powder

Aluminum nitride powder (AlN) is a wide bandgap semiconductor material composed of aluminum (Al) and nitrogen (N), with a hexagonal wurtzite structure.
High thermal conductivity: The theoretical thermal conductivity of aluminum nitride is as high as 320 W/m · K, which is several times that of aluminum oxide and suitable for the heat dissipation needs of high-power density electronic devices.
High resistivity: It has excellent electrical insulation performance and is suitable for scenarios such as electronic packaging that require high electrical insulation.
Low thermal expansion coefficient: Similar to the thermal expansion coefficient of silicon, it can avoid cracking problems caused by thermal stress.
Chemical stability: high temperature resistance, corrosion resistance, not easily corroded by most metals, suitable for applications in harsh environments.
High purity: Typically, the purity can reach over 99.5%, with extremely low impurity content, ensuring the stability of material properties.
