beryllium oxide tubes:
Beryllium Oxide tube, also known as Beryllia Ceramic tube, is a high-performance ceramic material with excellent thermal conductivity, high strength, and good electrical insulation properties. It is commonly used in high-temperature and high-pressure applications due to its resistance to extreme environments.

The Beryllium Oxide pipe is a cylindrical structure made from Beryllia Ceramic, which is a sintered form of Beryllium Oxide. The tube has a smooth surface finish and a uniform composition, ensuring high reliability and consistent performance.

With a length of 200 millimeters, the Beryllium Oxide tube is suitable for a wide range of industrial applications, such as in the aerospace, electronics, and medical industries. It can be used as a protective housing for sensitive components, as a heat sink for electronic devices, or as a crucible for high-temperature melting processes.

Overall, the Beryllium Oxide tube offers unmatched thermal management capabilities and durability, making it an ideal choice for demanding applications that require precision and reliability.

Application of beryllium oxide tubes

Due to its excellent performance in thermal, electrical, nuclear and mechanical aspects, beryllium oxide ceramics can be used as bracket parts and assemblies in the aerospace field, neutron moderators and radiation protection materials in atomic reactors in the nuclear industry, high performance, high power microwave packages and broadband high power electric vacuum devices, and crucible for melting rare and precious metals, such as uranium and plutonium. It can also be used as a refractory material for the refractory support rod of heating elements, etc., which has excellent applications in various fields.
