Aluminum nitride is a kind of high thermal conductive advanced industrial ceramic, to meet the needs of different fields, appropriate sintering additive and process can be selected to achieve required properties.

1. With high thermal conductivity, up to 230W/(℃*m), small thermal expansion coefficient, only around 4*10-6/℃, which is closed to silicon thermal expansion, also the thermal shock resistance is good.

2. Good electric insulation, electrical resistivity is higher than 1014Ω*cm,  breakdown voltage is larger than 15KV/mm, so it has large current carrying capacity.

3. Low dielectric constant and dielectric loss, which can reduce the energy loss during signal transmission.

4. AlN can resist erosion of various acid, alkali and other chemical substances, corrosion resistance is very good.

5. AlN material is non-toxic and harmless, meeting the requirements of safety and environmental protection.

6. AlN has high mechanical strength, good toughness, strong resistance to mechanical impact.

1. Semiconductor industry

Aluminum nitride ceramic substrate has the highest thermal conductivity among ceramic substrates, also with good corrosion and high temperature resistance,  it is widely used in semiconductor parts and integrated circuits, including integrated circuit (IC), radio frequency (RF) devices, high power LED,  piezoelectric components, photoelectric components, sensors, MEMS and other micro electronic devices.

2. Mechanical engineering and chemical industry

Aluminum nitride can be made into a variety of mechanical parts, including heat radiator, heat exchanger, heater, etc., which is widely used in scenarios those need fast heat transfer and corrosion resistance.
