Description

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.


BeO provides all the desirable physical and dielectric characteristics exhibited by aluminum oxide or aluminum nitride and, 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 diamond.
