beryllium ceramic, BeO ceramic has high thermal conductivity, high melting point (2530 ± 10°C), high strength, high insulation, high chemical and thermal stability, low dielectric constant, low
dielectric loss, and good adaptability properties, etc. widely used in special metallurgy, vacuum electronics, nuclear technology, microelectronics, and optoelectronics. Especially in high-power
semiconductor devices, integrated circuits, package microwave vacuum devices, and nuclear reactors, BeO is a mainstream ceramic material for the preparation of high thermal conductivity
components. The thermal conductivity of BeO ceramics in insulating materials is second only to of diamonds, and the theoretical value of thermal conductivity is as high as 325 W/(m•K), which is
the highest among all practical ceramic materials at present and is higher than that of AlN 180 W/(m•K). The theoretical value of thermal conductivity is as high as 60~80%, which is a magnitude
higher than that of Al2O3 ceramics.
BeO ceramics are also widely used in broadband internet and high-power electric vacuum devices such as transmission windows, clamping bars, and buck collectors of traveling-wave tubes. Low
dielectric constants and losses facilitate good broadband matching and reduce power loss. The high thermal conductivity allows the heat generated in high-power devices to be conducted promptly to
ensure the stability and reliability of the device. Compared with Al2O3 windows, BeO ceramics can withstand much larger continuous-wave output power. For example, The BeO window suffers no damage
to the output power of 263 kW, while the Al2O3 window breaks at an output power of 100 kW.
Lighter weight and higher thermal conductivity than aluminum stronger than steel performs reliably in cryogenic environments high heat tolerance-magnetic high neutron reflectivity & low neutron
absorptionHardens and strengthens other metals when used in alloys advanced aerospace equipment, military jets, delicate satellites and space structures -- the remarkable properties of beryllium
metals have been proven to perform in these demanding applications. With high strength and stiffness, low density, heat resistance, and exceptional reflectivity, beryllium metals deliver
reliability and sustainability in both everyday and extreme circumstances.

High thermal conductivity and low dielectric constant are the real reasons that BeO materials were widely used in electronic technologies, BeO ceramic is currently used in high-performance,
high-power microwave packages, BeO substrates have also been used for high circuit density multi-chip components, Use BeO material to dissipate the heat generated in the system in time to ensure
the system stability and reliability.
Metalized thick film lithographic substrates on BeO substrates are well suited for high-reliability high-density microwave circuits. These substrates can be Working under conditions above
44 GHz for Tel-communications, live broadcasts, Satellite communication modules, mobile phones, personal communication services, base stations, advanced avionics, and Global Positioning System
(GPS). Size can be and space scales as small as 0.001 inches, and routinely mounted in 4 x 4 Inches on the substrate. SiC-reinforced
aluminium metal matrix composites combined with DBC- BeO substrate has been successfully used for high current IGBT (insulated gate bipolar transistor). The design of the module substrate. Al/
SiC material combines high heat Dissipative, low aluminum alloy density and low coefficient of thermal expansion, and BeO The substrate is matched so that the thermal stress at the joint is
reduced.
