Beryllium Oxide

Beryllium Oxide (BeO)

BeO is the best candidate for extreme temperatures and watt density.  Heaters can be developed with Watt Densities of up to 800 watts per square inch and that can reach temperatures over 500°C.  This high performance substrate has excellent thermal conductivity, which produces an extremely uniform heater.
