|Material||AlN, aluminum nitride|
|Appearance||White, Light Grey|
Supplying aluminum nitride substrates with various surface finishing and metalization processes. Aluminum nitride ceramic is a great material for substrates for the electronics and semiconductor industry.
Aluminum nitride, AlN, is a light grey or white ceramic material which has a density of 3.26g/cm3.
Due to its high thermal conductivity and great electrical insulation, AlN was used in microelectronic industries.
Surface oxidization happened in the air even for room temperature, however, the aluminum oxide layer can protect the material up to 1370 C. Metallization methods are available to allow aluminum nitride to be used in electronics applications similar to those of alumina and beryllium oxide.
The hardness of aluminum nitride ceramic is even higher than alumina, the traditional technical ceramic, making it an ideal material for applications that require good wear resistance.
* Very high thermal conductivity (> 170 W/mK)
