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.

5 FAQs of High Thermal Conductivity Aluminium Nitride AlN Ceramic Plate/tube/Rod for Electronic Modules

What is aluminum nitride ceramic? Aluminum nitride (AlN) ceramic is a material with high thermal conductivity. It moves heat efficiently in electronic devices. It works well in circuits, power modules, and LED systems. The material resists electricity, making it safe for electronics.

Why pick AlN over alumina or beryllia? AlN conducts heat better than alumina. Alumina’s thermal conductivity is lower. Beryllia performs similarly but is toxic. AlN is safer and offers good insulation. It handles heat better in tight spaces. This makes it ideal for modern electronics needing cooling solutions.

Where is AlN ceramic used? AlN plates, tubes, and rods are common in electronics. They cool high-power LED lights, semiconductor chips, and laser diodes. The material also works in aerospace and automotive systems. It manages heat in parts like motor drivers and sensors. AlN prevents overheating in devices that run long hours.

What temperatures can AlN handle? AlN works in temperatures up to 1300°C in inert environments. In air, it stays stable below 700°C. Higher temperatures cause surface oxidation. This limits its use in oxygen-rich high-heat settings. For most electronics, its range is more than enough.

Is AlN safe to handle? AlN is non-toxic. Unlike beryllia, it poses no health risks during normal use. Cutting or grinding AlN creates dust. Workers should wear masks and gloves. Proper ventilation keeps the workspace safe. No special disposal steps are needed.
