What is beryllium oxide used for?
Beryllium oxide is used as many high-performance semiconductor parts for applications such as radio equipment. Used as a filler in some thermal interface materials such as thermal grease. Power semiconductor devices have used beryllium oxide ceramic between the silicon chip and the metal mounting base of the package to achieve a lower value of thermal resistance. Also used as a structural ceramic for high-performance microwave devices, vacuum tubes, magnetrons, and gas lasers.
