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 Ceramic Ring AlN Electrical Ceramic Washer/Gasket

1. What is Aluminum Nitride Ceramic? Aluminum Nitride (AlN) is a ceramic material known for moving heat efficiently. It works well in electronics and industrial parts because it insulates electricity while moving heat away. This makes it useful for devices needing heat control without electrical risks.

2. Why pick AlN over other ceramics like alumina? AlN moves heat much better than alumina. Alumina’s thermal conductivity is around 30 W/mK. AlN’s is 150-180 W/mK. This means AlN parts cool faster. AlN also matches silicon’s thermal expansion, reducing stress in semiconductor setups. It lasts longer under heat cycles.

3. Can AlN handle high temperatures? Yes. AlN works in temperatures up to 1300°C in non-reactive settings. In air, it resists oxidation up to 700°C. It stays stable in most electronics and machinery environments. Avoid extreme thermal shocks to prevent cracks.

4. Is AlN safe for electrical insulation? AlN does not conduct electricity. Its dielectric strength is 15-20 kV/mm. Volume resistivity is over 10^14 Ω·cm. This makes it reliable for high-voltage applications. It keeps circuits safe while managing heat.

5. How to install AlN washers correctly? Clean surfaces before placing the washer. Ensure even pressure to avoid cracks. Do not overtighten screws or bolts. Check for wear or damage during maintenance. Store AlN parts in dry conditions to prevent moisture absorption. Do not expose them to sudden temperature changes.
