Overview of Aluminum Nitride Powder / AlN Powder with High Sintering Activity

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 Powder / AlN Powder with High Sintering Activity

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.

Specifications of Aluminum Nitride Powder / AlN Powder with High Sintering Activity

This Aluminum Nitride Powder (AlN Powder) delivers exceptional performance for demanding applications. It features high sintering activity. This means the powder densifies effectively at lower temperatures. You achieve strong, reliable ceramic components easier. The powder boasts very high purity. Minimal impurities are present. This purity is crucial for top electrical insulation and thermal management.

The powder particles are very fine and uniform. A tightly controlled particle size distribution is maintained. Small, consistent particles pack together densely. They promote better sintering and a finer final microstructure. Low oxygen content is another key specification. Less oxygen improves thermal conductivity significantly. High thermal conductivity is a major reason AlN is chosen.

Typical specifications include an average particle size (D50) often below 1 micron. The specific surface area is high, indicating fine particles. Oxygen content is kept very low, usually under 1.0%. This low oxygen directly translates to excellent thermal conductivity values. Expect thermal conductivity exceeding 170 W/m·K in the sintered part. The powder’s high purity also ensures superb electrical insulation properties.

This high-activity AlN powder is ideal for manufacturing advanced ceramic substrates. These substrates are used extensively in high-power electronics. Power modules, LED packages, and semiconductor bases benefit greatly. The powder is also perfect for making thermally conductive fillers. It enhances heat dissipation in polymers and composites. Its properties make it vital for applications needing efficient heat spreading and electrical isolation. The powder enables reliable performance in critical thermal management systems.

Applications of Aluminum Nitride Powder / AlN Powder with High Sintering Activity

Aluminum Nitride powder with high sintering activity is very useful. This powder makes strong, dense ceramic parts easier. High sintering activity means the powder particles bond tightly at lower temperatures. This saves energy during production. It also makes the final ceramic material better.

The main use is in electronics. It works great for circuit boards needing to handle lots of power. AlN ceramic stops electricity but moves heat very well. This keeps powerful electronic parts like LEDs, lasers, and computer chips cool. Overheating damages these parts. AlN substrates prevent that. The high sintering activity ensures the boards are perfectly dense and reliable.

Heat management is another big area. AlN powder forms excellent heat sinks. These parts pull heat away from hot spots in devices. They are much better than older materials like alumina. Efficient heat spreading makes whole systems last longer and work better. The powder’s activity makes manufacturing these heat spreaders simpler and cheaper.

Special crucibles for melting metals also use this powder. AlN resists attack from harsh molten metals. Crucibles made from highly sintered AlN last a long time even in tough conditions. This is important for making pure metals and special alloys. The powder’s easy sintering helps create strong, long-lasting crucibles.

Optics and sensors benefit too. AlN parts are stable and handle heat well. This is good for devices needing precise light control. The powder’s quality ensures these parts perform consistently. Manufacturers choose this AlN powder because it makes production smoother. They get high-quality ceramic parts reliably. This powder solves heat problems in many advanced technologies.
