Materion Ceramics

Materion Ceramics is a Global Leader of Beryllium Oxide and High-Performance Engineered Ceramics offering heat dissapation.

Thermal conductivity second only to diamond among electrically insulating materials, dissipating 325 W/mK at room temperature.
A thermal coefficient of expansion (TCE) with 9 ppm/K intermediate to silicon or gallium arsenide and metals.
Electrical resistivity and dielectric strength equivalent to competitive materials.
Low dielectric constant (6.7) and low loss index (.0012 at 1 MHz) permitting improved circuit performance at high frequencies.
An inherent stability in oxidizing and reducing high dew-point atmospheres, unlike nitrides, which will decompose to their oxide equivalent.
Hermetic, high stiffness and a low weight are excellent properties of BeO.
Various forms and metallisation are available.
Handling BeO ceramic in solid form poses no special health risk
