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 Round AlN Aluminum Nitride Ceramic Plate

What is Round AlN Aluminum Nitride Ceramic Plate used for? Round AlN plates handle high heat in electronics. They move heat away from parts like LEDs, power modules, or semiconductor devices. The material insulates electricity, so it stops short circuits. This makes them good for heat sinks, circuit boards, and industrial tools needing temperature control.

How does aluminum nitride compare to alumina or beryllia ceramics? Aluminum nitride moves heat better than alumina. It works almost like beryllia but is safer. Beryllia is toxic when machined. AlN avoids this risk. It still keeps strong electrical insulation and resists chemical damage.

What temperatures can Round AlN Ceramic Plates handle? These plates work from -40°C to over 1200°C. They stay stable in extreme heat. This suits furnaces, laser systems, or high-power electronics. The material doesn’t crack easily under rapid temperature changes.

Are there handling precautions for AlN plates? AlN is brittle. Avoid dropping or hitting the plates. Use gloves to prevent oil from skin affecting performance. Clean surfaces with alcohol or mild soap. Don’t use rough scrubbers. Store plates separately to prevent scratches.

Can Round AlN Plates be customized? Yes. Sizes and thicknesses vary based on needs. Holes, grooves, or coatings like metallization are added for specific uses. Custom shapes take longer but are possible. Most suppliers offer samples to test before bulk orders.
