Beryllium oxide ceramics are ceramics with beryllium oxide (BeO) as the main component. Mainly used as materials for large-scale integrated circuit substrates, high-power gas laser tubes, heat sink shells of transistors, microwave output windows and neutron moderators.
Ceramic beryllium oxide BeO
Beryllium oxide (BeO) ceramics have the characteristics of high thermal conductivity, high melting point, high strength, high insulation, high chemical and thermal stability, low dielectric constant, low dielectric loss and good process adaptability. It is used in special metallurgy, Vacuum electronics technology, nuclear technology, microelectronics and optoelectronics technology are widely used.
Basic properties
High strength over a wide temperature range
High hardness
Low friction coefficient
Excellent wear resistance
