Aluminum nitride (AlN)
AlN is hexagonal and is typically gray or off-white. Aluminum nitride is a ceramic material with a variety of excellent properties, such as high thermal conductivity, good electrical insulation, low dielectric coefficient and dielectric losses, non-toxicity and matched thermal expansion coefficient to silicon. It is a ceramic material of a brand new type with excellent overall performance.
Aluminum nitride exhibits a thermal conductivity of 320 W/m*K, which is comparable to BeO and SiC. It is also more than 5 times as high as Al2O3
(2) The thermal expansion coefficient of Aluminum Nitride (4.5×10-6degC), is the same as that of Si (3.5-2×10-6degC), or GaAs (6×10-6degC);
Aluminum nitride has excellent electrical properties (dielectric constant dielectric loss volume resistivity dielectric strength).
Aluminum nitride (4) has excellent mechanical properties. It is stronger than Al2O3 ceramics and BeO ceramics and can be sintered with atmospheric pressure.
Aluminum nitride is a good optical transmittance material.
2. Aluminum nitride is a ceramic substrate with high thermal conductivity. It has a low expansion coefficient and high strength. It is an excellent large-scale heat dissipation and packaging substrate.
The hardness of aluminum nitride is much higher than traditional alumina.
4. AIN ceramics have excellent heat resistance, melt-erosive resistance, and thermal shock resistance. They can be used to manufacture GaAs crucibles for crystals, Al evaporating dish, magnetic fluid power generator devices, high temperature turbines corrosion-resistant components, and their optical properties can even be used as an infrared glass. Aluminum nitride can be made into ultra-large-scale integrated substrates, high-frequency piezoelectric components and other products.
5. Aluminum nitride resists heat, is resistant against corrosion caused by molten steel, is stable with acid but easily corroded when in an alkaline solution. When exposed to humid air, AIN’s new surface will form a very fine oxide film. It can be used to melt aluminum, copper silver, lead, and other metals using this feature. AIN ceramics can be used to replace toxic ceramics made of beryllium dioxide and have good metallization characteristics. They are also widely used in electronics.
