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.
Beo Ceramic Metallization:
Ceramic + Mn-Mo plating
Ceramic + Ni plating
Ceramic + AG plating
Ceramic + Au plating
Ceramic + Sn plating
Ceramic + AG+Ni+Au or Sn plating.
Beryllia Properties:
1.Superior Thermal Conductivity(Can reach to 240W/m.k)
2.More Consistent Heat Dissipation
3..Better Uniformity of Crystalline Structure
4.Easy and Effective Metallization
5.More Durable in Semiconductor Chamber Cleaning Environments
