Beryllium oxide is a white ceramic material that looks very similar to other ceramics such as alumina. It is an excellent electrical insulator, but has unique thermal conductivity. It is suitably used as an endothermic insulating material in electronic devices. For example, when assembling a power transistor,IGBT or high power components, Beryllium oxide substrate has a good heat sink function,which is much better than using a fan, a heat pipe or a large number of fins. Therefore, Beryllium oxide is mostly used in a variety of high-power electronic circuit systems and microwave radar devices such as klystrons or traveling wave tubes.
The new use of Beryllium oxide is used in certain lasers, especially in argon lasers, to meet the increased power requirements of modern lasers.
