Product Description
BeO Ceramic Products
Beryllium oxide (BeO) ceramic materials are in high demand due to their superior performance at high temperatures along with a thermal conductivity second only to diamond among insulating materials.We offer solutions to any component that must provide high thermal conductivity in conjunction with electrical resistivity.  Building on our unique combination of materials forming, firing and fabrication technologies, we are rapidly expanding our product portfolio to provide the next generation of beryllia ceramic materials.
The physical size of the device or the enclosure is reduced. 
The device is exposed to high ambient temperatures
Airflow or liquid cooling is not practical or prohibitively expensive
Ideal materials for heat sinks in electronic circuits
