Beryllia ceramics convey an exceptional combination of properties:

  • Second only to Diamond among electrical insulating materials, premium BeO ceramics provide an exceptionally high thermal conductivity ranging from 275 to 325 W/m•K at room temperature.

  • Low Dielectric Constant (6.7) and low tanδ dielectric loss tangent (.0004 at 1 MHz), permitting improved circuit performance at high frequencies.

  • A Coefficient of Thermal Expansion (CTE) of 9 ppm intermediate to silicon or gallium arsenide and metals.

  • Ten times greater thermal conductivity than alumina ceramics.
