Aluminum nitride (ALN)ceramic, which is a advanced ceramic, has a series of brilliant characteristics, the core advantages are superb thermal conductivity, reliable electrical insulation, and that is similar to thermal expansion coefficient of silicon (Si), what fields it can be applied in?
Heat dissipating substrates and electronic device packaging are the main applications of aluminum nitride ceramics. Thanks to excellent thermal conductivity, thermal expansion coefficient close to silicon, high mechanical strength, good chemical stability and environmental protection and non-toxic of AIN ceramics, It is considered to be an ideal heat transfer and spreader material of new generation of thermal substrate and electronic device packaging, very suitable for mixed power switch packaging and microwave vacuum tube package, but also the ideal material for large-scale integrated circuit substrate.
Electrostatic vacuum chuck for wafer processing are a common application of a structural ceramic. Aluminum nitride structure ceramics have good mechanical properties, high hardness, toughness better than Al2O3 ceramics, and high temperature and corrosion resistance. Using AIN ceramic heat resistance and corrosion resistance, it can be used to make crucible, evaporation pan and other high temperature corrosion resistance parts.
Aluminum nitride can be used to manufacture high-frequency and high-power devices with at high temperatures or in the presence of certain radiation conditions, such as high-power electronics and high-density solid-state memory. As one of the third generation semiconductor materials, aluminum nitride has not only broad-band gap, high thermal conductivity, high resistivity, but also good ultraviolet transmittance, high breakdown field strength and so on.
AlN has a band-gap of 6.2eV and strong polarization effect. It is widely used in mechanical, microelectronics, optics and SAW manufacturing, high frequency broadband communication fields, such as aluminum nitride piezoelectric Ceramic parts and ceramic films. In addition, high-purity AlN ceramics are transparent and such material has excellent optical properties with combination of their electrical properties, They are extensively used as functional components such as infrared deflectors and sensors.
As a heat-resistant material, AlN can be used to make crucible, protective tube, casting mold, etc. Aluminum nitride can be in 2000℃ non-oxidizing atmosphere, still has stable performance, is an excellent high temperature refractory material, resistant to molten metal erosion ability.
Aluminum nitride ceramics have high thermal conductivity, low thermal expansion coefficient, excellent thermal conductivity efficiency and thermal shock resistance, and can be used as thermal shock and heat exchange materials, such as aluminum nitride ceramics can be used as heat exchange equipment materials for Marine gas turbines and heat resistant components of internal combustion engines. Due to the excellent thermal conductivity of aluminum nitride material, the heat transfer capacity of heat exchanger is effectively improved.
Aluminum nitride has excellent electrical insulation, high thermal conductivity, good dielectric properties, good compatibility with polymer materials, is an excellent additive of polymer materials for electronic products, can be used in TIM filler, FCCL thermal dielectric layer filler, widely used in electronic devices heat transfer medium, thereby improving work efficiency. For example, the heat transfer medium at the gap between the CPU and the radiator, the high-power transistor and the thyristor element in contact with the substrate.
JingHui Industry is a professional manufacturing for making aluminum nitride ceramics, the AlN products we supplied mainly cover Ceramic Substrates, ceramic heat sinks and AlN structural ceramic parts with high accuracy dimensional.
