BeO is also commonly referred to as beryllia.
It is produced as a white amorphous powder and sintered into larger shapes.
Impurities like carbon, trapped with the crystals can give a variety of colors to this material.
Sintered BeO is a very stable ceramic and is used in a variety of applications where both high thermal conductivity and electrical resistivity is needed.
Electrical isolation is equal to that of alumina and the best electrical insulators.
A 20% lower dielectric constant than alumina and aluminum nitride offers advantages in the high-frequency field.BeO ceramic is utilized for its proven superior properties and its cost effectiveness unmatched by aluminum nitride, aluminum oxide, boron nitride, silicon carbide or any ceramic.
