The plates are commonly made of alumina, but when large lateral heat transfer is required, higher thermal conductivity materials such as beryllia and aluminum nitride are desired.

Beryllia (beryllium oxide or BeO) is lightweight, very rigid and has excellent thermal management properties -- meaning it withstands extreme temperatures and rapidly dissipates heat better than any other ceramic material, making it useful in heat producing circuits, such as those carrying high currents or very dense circuitry.
