Beryllium Oxide (BeO), commonly referred to as beryllia, possesses a unique combination of thermal, dielectric, and mechanical properties which are highly desirable in electronic applications. No other material exhibits these characteristics. BeO ceramic conducts heat better than most metals, exhibits extremely low dielectric loss characteristics, possesses high electrical resistivity, and offers excellent strength properties. It provides all the desirable physical and dielectric characteristics exhibited by aluminum oxide and, in addition, offers higher thermal conductivity and lower dielectric constant.
