Aluminum Nitride Ceramic (AlN) is a special ceramic material that combines high thermal conductivity with high electrical resistivity. Only a few ceramics possess high thermal conductivity: Such as Beryllium Oxide (BeO) and cubic Boron Nitride (c-BN) are virtually the only other examples. However, the use of BeO is restricted due to its powder toxicity, and c-BN is very difficult to produce.
Also, the material is suitable for further processing with thick and thin-film technology aluminum nitride is an ideal material for applications in telecommunications technology.
Aluminum nitride ceramic is therefore used as a substrate for semiconductors, as well as for high-power electronic parts, housings, and heat sinks.
