Beryllia ceramic (Beryllium Oxide, or BeO) was developed in the 1950s as a space-age technical ceramic material, and it offers a unique combination of properties not found in any other ceramic material. It has a special combination of thermal, dielectric, and mechanical properties, making it very desired for use in electronic applications. These features are unique to this material. BeO ceramic has superior strength, exceptionally low dielectric loss characteristics, and conducts heat more effectively than most metals. It offers greater thermal conductivity and a lower dielectric constant in addition to Alumina's favorable physical and dielectric properties.
It is an ideal material for applications requiring high heat dissipation as well as dielectric and mechanical strength due to its excellent thermal conductivity. It is especially well suited for use as a diode laser and semiconductor heat sink, as well as a rapid thermal transfer medium for miniaturized circuitry and tightly contained electronic assemblages.
