Beryllium Oxide Ceramics

Beryllium Oxide (BeO), which is commonly referred to as Beryllia, is endowed with a virtuously unique combination of thermal, electrical, optical, and mechanical properties which may be exploited for a diverse range of applications from thermal management systems for integrated electronics to high-performance refractory components for nuclear reactors.

Applications of Beryllium Oxide Ceramics

No other oxide ceramic material collectively exhibits these highly desirable properties and characteristics. BeO ceramic conducts heat more quickly than virtually all metals with the exception of copper and silver. Beryllia exhibits extremely low dielectric loss characteristics, possesses high electrical resistivity, and offers excellent strength with high specific stiffness properties. BeO provides all the desirable physical and dielectric characteristics exhibited by an aluminum oxide or aluminum nitride, in addition, offers thermal conductivity ten times higher than alumina, and fifty percent higher than aluminum nitride, a dielectric constant that is lower than both alumina and aluminum nitride, and weight per given volume that is fully a quarter less than alumina, and nearly ten percent less than aluminum nitride. As a thermally conductive and electrically insulating material, its performance is exceeded only by that of the diamond.
