Aluminum Nitride

Aluminum Nitride (AlN) Description

Aluminum nitride (AlN) melts at 2800 °C. It has high thermal conductivity, excellent electrical insulation, low dielectric constant and dielectric loss. The thermal conductivity of aluminum nitride is 5 to 10 times that of the traditional substrate material aluminum oxide, which is close to the thermal conductivity of beryllium oxide.

The series of excellent characteristics are considered to be the ideal materials for highly concentrated semiconductor substrates and electronic device packaging. It can be used in a wide range of applications, such as optics, lighting, electronics and renewable energy.
