Beryllium oxide ceramics offer many benefits over competing materials. They can be nine times more thermally conductive than aluminum nitride (AlN) ceramic, a commonly used alternative. Additionally, BeO has a thermal conductivity of up to 325 W/(m•K), meaning beryllia can be up to 80 percent more thermally conductive than AlN materials. Beryllium oxide ceramic is more chemically stable than AlN ceramics in environments containing oxidizing chemicals.
