Beryllium oxide is white, refractory, heat-resistant, flying in a current O2 and water vapor. Beryllium oxide is in a few reactive calcined.
The combination of high thermal conductivity and low thermal expansion coefficient can be used beryllium oxide as a heat-resistant material with significant chemical inertness.
