Overview of High Purity Aln Aluminum Nitride Powder Whitish Grey Powder for High Thermally Conductive 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 High Purity Aln Aluminum Nitride Powder Whitish Grey Powder for High Thermally Conductive 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.

Specifications of High Purity Aln Aluminum Nitride Powder Whitish Grey Powder for High Thermally Conductive Ceramics

High purity aluminum nitride powder appears whitish grey. This powder is key for making advanced ceramics. Its main advantage is excellent heat transfer. You get ceramics moving heat nearly as well as metals. This matters for electronics needing cooling.

The powder’s purity is critical. We offer grades from 99% pure upwards. Higher purity means better performance. Impurities hurt thermal conductivity. Our powder minimizes unwanted elements like oxygen or carbon. This ensures the final ceramic works perfectly.

Particle size is another vital factor. Our powder comes in various sizes. Typical sizes are fine, like a few micrometers. Consistent particle size gives a uniform ceramic structure. A tight particle size distribution is best. This helps when shaping and sintering the material.

The powder packs well. Its tap density is high. This makes handling and processing easier. You need less powder to fill a mold. The powder flows freely too. This is important for automated production lines.

Surface area is controlled carefully. Specific surface area impacts how the powder sinters. We balance surface area for optimal densification. Getting full density in the ceramic is essential. Full density gives the best thermal conductivity.

Moisture is a problem. This powder can absorb water from the air. Store it sealed in a dry place. Handle it carefully to avoid moisture pickup. Damp powder degrades and performs poorly later.

This AlN powder suits demanding applications. Use it for heat sinks in powerful electronics. It works well in LED lighting substrates. It’s ideal for semiconductor processing equipment parts. High power modules rely on its cooling ability. Anywhere heat must move fast, this material helps. Manufacturers choose it for reliability and performance.

Applications of High Purity Aln Aluminum Nitride Powder Whitish Grey Powder for High Thermally Conductive Ceramics

High purity AlN aluminum nitride powder appears whitish grey. This powder matters for making advanced ceramics. These ceramics move heat extremely well. AlN ceramics beat regular alumina ceramics here. They move heat over ten times better. This ability helps a lot in electronics needing serious cooling.

AlN ceramics also stop electricity. This makes them perfect for insulating parts in powerful electronics. Think semiconductor packaging, especially for high-power devices. Engineers use AlN substrates and heat sinks here. The AlN moves heat away fast from sensitive chips. This prevents overheating and failure. It keeps devices reliable. It lets them work at higher power levels safely.

The powder also works for making ceramic parts handling molten metals. Crucibles and setters use AlN. Its high heat tolerance and chemical stability are key. It doesn’t easily react with those hot metals. AlN ceramics also serve as heat spreaders. They sit between hot components and metal heat sinks. The AlN moves the heat into the metal sink efficiently.

AlN powder is vital for LED lighting too. LED chips generate intense heat in small spots. AlN ceramic substrates under the chip pull this heat away quickly. This protects the LED. It makes the light last longer. It keeps the color bright and stable. High purity is essential for these uses. Impurities hurt the heat-moving ability. Pure AlN powder ensures the best ceramic performance. This powder enables tough, reliable parts where heat management is critical.

5 FAQs of High Purity Aln Aluminum Nitride Powder Whitish Grey Powder for High Thermally Conductive Ceramics

High Purity AlN Aluminum Nitride Powder FAQs

What exactly is this AlN powder?
This is a very pure aluminum nitride powder. It looks whitish-grey. Its main strength is moving heat very well. This makes it perfect for making special ceramics. These ceramics need to handle lots of heat.

Why pick AlN powder over other ceramics?
Heat moves through AlN ceramics much faster. AlN moves heat much better than regular alumina ceramics. This is crucial for electronics. Electronics get hot. AlN helps pull that heat away fast. It stops parts from overheating and failing.

How pure is this powder?
Our powder is high purity. Typical purity levels are 99% or higher. This high purity is vital. Impurities hurt the thermal conductivity. Less impurity means the final ceramic moves heat better. You get the performance you need.

Is AlN powder safe to handle?
Handle it carefully. The powder itself is stable under normal conditions. Always wear protection. Use gloves and a dust mask. Avoid breathing the dust. Keep it away from strong acids or bases. Follow standard lab safety rules.

Does particle size matter?
Particle size is very important. Finer powder usually sinters better. Sintering makes the powder turn into solid ceramic. The right particle size gives a dense ceramic piece. A dense piece moves heat best. We offer different size options. Choose based on your production method.
