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 Aluminum Nitride AlN Ceramic Discs

High Thermal Conductivity Aluminum Nitride AlN Ceramic Discs are advanced materials used in electronics. They manage heat efficiently. They are made from aluminum nitride powder. This powder is sintered at high temperatures. The discs have high thermal conductivity. They also have strong electrical insulation. They resist wear and corrosion.

People often ask what thermal conductivity AlN ceramic discs offer. These discs have a thermal conductivity of 170-200 W/mK. This is much higher than alumina ceramics. Alumina ceramics typically have 20-30 W/mK. Aluminum nitride is closer to beryllia in performance. Beryllia has around 280 W/mK. But beryllia is toxic. Aluminum nitride is safer.

Many want to know where these discs are used. They are common in electronics. Examples include LED lighting and semiconductor devices. They are used in power modules for electric vehicles. They handle heat in aerospace systems. Industrial equipment uses them for high-temperature stability.

People ask why choose AlN over aluminum oxide or metals. Aluminum nitride transfers heat better than aluminum oxide. It insulates electricity better than metals like copper. It resists thermal shock. It works in extreme temperatures. It does not corrode easily. It is lighter than metals. It lasts longer under stress.

A frequent question is about handling AlN ceramic discs. The material is stable but brittle. Avoid dropping or applying sudden force. Machining requires diamond tools. Standard tools wear out quickly. No special storage is needed. Keep them dry. Avoid contact with strong acids or alkalis. They can damage the surface.

Another common question is about temperature limits. AlN discs handle up to 1000°C in air. In inert gases they withstand 1400°C. Thermal cycling does not crack them. They expand minimally when heated. This prevents stress in devices.
