Overview of aluminum nitride ceramics

Aluminum Nitride Ceramic is an advanced ceramic material with aluminum nitride as the main component. It has been widely used in electronics, optics, and mechanics due to its unique properties.

Features of aluminum nitride ceramics

High thermal conductivity: Aluminum nitride ceramics have relatively high thermal conductivity, usually between 170-260 W/m·K, which makes it an excellent heat dissipation material. It is especially suitable for electronic devices that require efficient heat dissipation, such as substrate materials for power semiconductor devices.

Good electrical insulation: Despite its high thermal conductivity, aluminum nitride ceramics are excellent insulators of electricity, which can effectively prevent current leakage and ensure the safe operation of electronic components.

Low dielectric constant and dielectric loss: These characteristics make aluminum nitride ceramics very suitable for use in high-frequency circuits because it can reduce energy loss during signal transmission.

High temperature resistance: Aluminum nitride ceramics can maintain structural stability and strength at extremely high temperatures. Its melting point is about 2800°C, so it is suitable for applications in high temperature environments.

Low thermal expansion coefficient: Compared with semiconductor materials such as silicon, aluminum nitride has a lower thermal expansion coefficient, which means it has better dimensional stability when the temperature changes, which helps improve packaging reliability.

Corrosion resistance: Aluminum nitride ceramics have good chemical stability to most molten metals and are not easily oxidized or corroded, allowing them to perform well in harsh environments.

High mechanical strength: Although not as hard as some other types of ceramic materials, aluminum nitride ceramics still provide enough mechanical strength to allow them to be used in many structural applications.
