Overview of China Polished Aluminum Nitride Ceramic Part Used in Electrical Industry

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 China Polished Aluminum Nitride Ceramic Part Used in Electrical Industry

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 China Polished Aluminum Nitride Ceramic Part Used in Electrical Industry

China’s polished aluminum nitride ceramic parts serve critical roles in demanding electrical applications. These components offer exceptional thermal conductivity. Heat moves away from sensitive electronics efficiently. Electrical insulation remains high even at elevated temperatures. This prevents current leakage. Aluminum nitride ceramics resist corrosion well. They handle harsh chemical environments without degrading. Mechanical strength is also impressive. Parts withstand significant physical stress during operation.

Material purity is a key specification. High-purity aluminum nitride powder ensures optimal performance. Typical purity levels exceed 99%. This minimizes impurities affecting thermal or electrical properties. Thermal conductivity is paramount. Values often range between 170 and 220 W/m·K. This rivals metals like aluminum. The thermal expansion coefficient closely matches silicon. This reduces stress in semiconductor packaging. It prevents cracking during temperature changes.

Surface finish is crucial for electrical contacts. Precision polishing achieves very smooth surfaces. Ra values below 0.1 micrometers are common. This ensures good contact with other components. It minimizes electrical resistance at interfaces. Electrical resistivity is extremely high. Values typically exceed 10^14 Ω·cm. This provides excellent isolation for circuits. Dielectric strength is also high. Parts resist electrical breakdown under high voltage.

Mechanical properties support reliability. Flexural strength usually exceeds 300 MPa. This allows thin, complex shapes without breaking. Hardness is high on the Mohs scale. The material resists wear and abrasion effectively. Density is relatively low. This helps in weight-sensitive applications. Operating temperature capability is broad. Parts function reliably from cryogenic levels up to around 1400°C. They maintain properties across this range.

These specifications make polished AlN ceramics ideal for high-power electronics. They are found in semiconductor manufacturing equipment. Power modules use them for substrates and heat spreaders. High-frequency applications rely on their stable dielectric properties. Laser diode carriers benefit from their thermal management. The material enables smaller, more powerful electronic devices.

5 FAQs of China Polished Aluminum Nitride Ceramic Part Used in Electrical Industry

What is aluminum nitride ceramic?
Aluminum nitride ceramic is a special material. It handles heat very well. Electricity doesn’t pass through it easily. It’s strong and doesn’t react with many chemicals. These features make it good for tough electrical jobs.

Why use it in electrical parts?
Electrical parts get hot. Aluminum nitride pulls heat away fast. This stops parts from getting too hot and breaking. It also keeps electricity safely inside where it belongs. It works much better than plastic or older ceramics at moving heat.

Where is it used most?
You see it inside high-power electronics. It’s used for holding computer chips (substrates). It’s used for insulating parts in big power devices. It’s used in circuits needing serious heat control. Semiconductor tools use it a lot.

Why is the polished surface important?
A smooth, polished surface is critical. It makes perfect contact with other parts. Good contact means heat transfers efficiently. It also prevents tiny air gaps causing problems. A rough surface doesn’t work nearly as well.

Can I get custom shapes from China?
Yes, Chinese manufacturers are very capable. They make many custom aluminum nitride parts. They cut, grind, and polish it to exact shapes. This includes complex designs needed for modern electrical gear. You get reliable parts at good prices.
