Beryllium Oxide (BeO)-Sputtering Target

Beryllium Oxide (BeO)-Sputtering Target introduce:

Characteristic

Beryllium oxide,  is an inorganic compound with the formula BeO. This colourless solid is a notable electrical insulator with a higher thermal conductivity than any other non-metal except diamond, and exceeds that of most metals. As an amorphous solid, beryllium oxide is white. Its high melting point leads to its use as a refractory material.

Application

Sintered beryllium oxide is a very stable ceramic.Beryllium oxide is used in rocket engines and as a transparent protective over-coating on aluminised telescope mirrors.




Beryllium oxide is used in many high-performance semiconductor parts for applications such as radio equipment because it has good thermal conductivity while also being a good electrical insulator. It is used as a filler in some thermal interface materials such as thermal grease.It is also used as a structural ceramic for high-performance microwave devices, vacuum tubes, magnetrons, and gas lasers. BeO has been proposed as a neutron moderator for naval marine high-temperature gas-cooled reactors (MGCR), as well as NASA's Kilopower nuclear reactor for space applications.
