Beryllium oxide (BeO, also known as beryllia) gives manufacturers numerous advantages for applications that require exceptional thermal conductivity. Until now, a lack of authoritative online resources about the material, has left those who would benefit from working with BeO unaware of its benefits and with inadequate or inaccurate facts. Materion Ceramics is setting the record straight with this infographic, which compares BeO to its nearest material peer (AlN). As the world’s only fully integrated developer and supplier of BeO ceramics, Materion supports product designers and engineers with accurate, extensive information on beryllium-based materials and components.

Beryllium Oxide (BeO) Ceramics: Key Facts and Figures

Beryllium oxide is known for the following key attributes:

  • High thermal conductivity
  • High electrical resistivity
  • High metallizing capability
  • Low dielectric constant

By the numbers:

  • 60% more thermally conductive than AlN
  • Thermal conductivity up to 325 W/(m∙K), second only to diamond among insulating materials
  • 1:1 cost comparison to AlN across hundreds of applications
  • Dielectric constant of 6.7, for improved circuit performance in dense circuitry and high frequency circuitry
  • Coefficient of thermal expansion (CTE) of 9 ppm/°C, allowing effective bonds with both silicon and base metals

Industries and applications using BeO:

  • Military and aerospace
  • Energy
  • Lasers
  • Microwave communications
  • High power electronics
  • Semiconductor processing
