Allgemeine Beschreibung

Beryllium oxide is a ceramic material with a unique combination of high electrical resistance and dielectric strength with high thermal conductivity. It also shows high transmission in a wide spectral range from VUV(vacuum UV) through IR. It is widely used in the field of optical devices and electronic transistors.

Anwendung

Beryllium oxide can be used as an additive to fabricate uranium dioxide kernels(nuclear fuel) with enhanced thermal conductivity.
