Application of aluminum nitride ceramic materials

What is aluminum nitride? ? Aluminum nitride This atomic crystal is a diamond-like Nitride, hexagonal crystal structure, wurtzite crystal structure, and non-toxic. Aluminum nitride has a high thermal shock value.
The miniaturization and advancement of electronic products has led to electronic circuits and systems that are capable of high integration density as well as high functionality. Electronic parts have increasingly stringent requirements for their carrier substrate. The breakthrough in high thermal conductivity has been achieved through high integration and miniaturization. It is becoming increasingly difficult for traditional alumina ceramic sub-substrates to meet the requirements of the development. Aluminum nitride, which has excellent chemical and physical properties, has slowly become the most popular choice in packaging materials.

Attenuation material for microwaves made of aluminum nitride
Microwave attenuation research and applications have gradually spread from military purposes to everyday life. It is a physical process that converts microwave energy into heat energy and then exchanges it to the environment. This is being used more frequently in high-power microwave vacuum devices.
AlN has low dielectric losses. AlN is suitable for use as a microwave-attenuating material because it contains metals or ceramics that are electrically and thermally conductive. These materials can then be used to make Al N-based microwave ceramics. Current research involves carbon nanotubes, TiB2, and TiC as conductive additives. Metals such Mo, W, Cu are also involved.
Aluminum nitride, heat-resistant material
Aluminum nitride does not wet with aluminum, calcium and other metals. This makes it ideal for use as a crucible or protective tube, casting mould, mold mold, etc. Aluminum nitride ceramics may be used in an immersion thermocouple protective tube as a metal pool. It is able to be used in the molten pools at 8001000 for up to 3000 hours and it will not corrode. destroy. Because aluminum nitride materials can withstand molten salt gallium senide and other substances, the crucible can now be replaced by glass to synthesize gallium senide semiconductors. This allows for complete elimination of silicon pollution and high-purity Gallium arsenide.
Aluminum nitride clays are very strong at room temperatures and do not react to temperature changes. They have high thermal conductivity, low thermal expansion coefficients and a relatively high thermal conductivity. It is both a heat-resistant material as well as a heat exchange material. It can be used to heat exchangers for gas turbines. Materials that are heat resistant and heat exchange.
AlN ceramic materials are versatile and have many potential markets. They can be used in electronic, electric power, locomotives and aviation.

Hardness of Aluminum Nitride Ceramics

What is Aluminum Nitride Ceramic?

Aluminum nitride clays are ceramics containing aluminum nitride, (AIN), as the main crystal phase. Aluminum nitride is a main raw material to produce high thermal conductivity aluminum-nitride ceramic substrates. It has high purity, small particles, and high activity.

Aluminum Nitride Ceramics’ Hardness

Aluminum nitride ceramics have become more widely used with the advances in science and technology. Aluminum nitride ceramics have many applications in today’s world, including aerospace, electronics, semiconductors, and other areas. Aluminum nitride cermics exhibit high strength, hardness and wear resistance. Aluminum nitride clays have a hardness second only to diamond.


Aluminum nitride is a key structural ceramic material. Its chemical formula is ALN. It is superhard and resists wear and oxidation at elevated temperatures. Aluminum nitride ceramics are possible to be made under normal pressure.


First of all, aluminum nitride cermics rank fourth in organic materials after diamond, cubic boron, and boron carbide. Hot-pressing sintering is the best way to obtain high-density aluminium nitride. It has excellent strength and oxidation resistance and can be maintained in place under high temperatures. It can be used for turbine blades in high-temperature, gas turbines. It can be used for wear-resistant sealing and can also be used in heating plates to heat silicon wafers in semiconductor manufacturing.


Aluminum nitride ceramics have a high hardness, making them difficult to process. If the equipment and technology required to process it are not available, it will be difficult. Every step of the process is vital. Material can be scrapped if it lacks craftsmanship.
