application of boron nitride ceramic

boron nitride is often referred to as “white graphite” because it is a lubricious material with the same platy hexagonal structure as carbon graphite. Unlike graphite, BN ceramic is a very good electrical insulator. boron nitride ceramic offers very high thermal conductivity and good thermal shock resistance. BN ceramics is stable in inert and reducing atmospheres up to 2000°C, and in oxidizing atmospheres to 850°C.
