Aluminum nitride
AlN

If high thermal conductivity and electrical insulation are required, aluminum nitride (AlN) is an excellent material, making it an ideal material for thermal management and electrical applications. In addition, aluminum nitride is a common alternative to beryllium oxide (BeO) in the semiconductor industry because it is not hazardous to health during processing.

Aluminum nitride can be stabilized up to 2200 ℃. The strength at room temperature is high, and the strength decreases slowly with the increase of temperature. It has good thermal conductivity and small coefficient of thermal expansion, so it is a good thermal shock resistant material. It is an ideal crucible material for melting and casting pure iron, aluminum or aluminum alloy. Aluminum nitride is also an electrical insulator with good dielectric properties. It is also promising to be used as electrical components.

Feature

The thermal conductivity is high (more than 150W / m · K), close to BeO and SiC, more than 5 times of that of Al2O3;
The thermal expansion coefficient (4.5 × 10-6 ℃) matches that of Si (3.5-4 × 10-6 ℃) and GaAs (6 × 10-6 ℃);
Various electrical properties (dielectric constant, dielectric loss, bulk resistivity, dielectric strength) are excellent;
The mechanical properties are good, the flexural strength is higher than that of Al2O3 and BeO ceramics, and can be sintered under normal pressure;
non-toxic;
It can be made by tape casting. It is a promising substrate and packaging material for high power integrated circuits.
