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.

Specifications of ALN Electric Aluminum Nitride Ceramic Sheet, Aluminum Nitride Ceramic Heat Sink

The ALN Electric Aluminum Nitride Ceramic Sheet and Aluminum Nitride Ceramic Heat Sink are designed for high-performance thermal management. The material is aluminum nitride (AlN), a ceramic with excellent thermal conductivity. This property allows rapid heat transfer, making it ideal for electronics needing efficient cooling. The thermal conductivity reaches 170-180 W/m·K, surpassing many traditional ceramics like alumina. This ensures stable operation in high-power devices.

The sheets and heat sinks handle extreme temperatures. They work reliably from -40°C to 1800°C, suitable for harsh environments. Their low thermal expansion coefficient matches silicon, reducing stress in semiconductor applications. This compatibility prevents cracking or warping during temperature changes. Electrical insulation is another key feature. The dielectric strength exceeds 15 kV/mm, preventing current leakage in high-voltage setups. Low dielectric loss ensures minimal energy waste at high frequencies.

Mechanical durability is critical. Aluminum nitride ceramics offer high hardness (Hv 1200) and flexural strength (300-400 MPa). They resist wear, corrosion, and chemical reactions, extending service life. Surface finishes include polished or as-sintered options. Polished surfaces enhance contact with heat sources, improving thermal transfer. Custom shapes and sizes are available. Thickness ranges from 0.3 mm to 30 mm, with diameters or lengths up to 200 mm.

Applications span industries. These components are used in LED lighting, power modules, laser diodes, and semiconductor equipment. The heat sinks efficiently dissipate heat from high-power LEDs or ICs, preventing overheating. In RF and microwave devices, the low signal loss ensures stable performance.

Customization supports specific needs. Options include metallization (gold, silver, aluminum) for soldering or brazing. Holes, grooves, or patterns can be added for assembly requirements. OEM services provide tailored solutions for unique projects.

Environmental safety is prioritized. Aluminum nitride is non-toxic, unlike beryllia ceramics. It meets RoHS standards, ensuring safe use in consumer electronics.
