Dry Pressed
Beryllium Oxide Ceramic
Dry Pressed
Beryllia ceramics convey an exceptional combination of properties:
- Second only to Diamond among electrical insulating materials, premium BeO ceramics provide a thermal conductivity dissipating nearly 325 W/mk at room temperature.
- Low Dielectric Constant (6.7) and low loss index (.0012 at 1 MHz), permitting improved circuit perfromance at high frequencies.
- A Coefficient of Thermal Expansion (CTE) of 9 ppm (BUI) intermediate to silicon or gallium arsenide and metals.
- Ten times greater thermal conductivity than alumina ceramics.
