Customized Beryllium Oxide (BeO) Ceramic Parts

To better serve you, we would like to discuss your specific requirement, Please Contact Us for a quote.

Beryllium Oxide (BeO), also known as beryllia, is one of the best ceramic for heat dissipation related applications. It has characteristics like high thermal conductivity, high melting point, high strength, low dielectric loss, etc. BeO ceramic also has the combination of low density and high neutron moderation and reflection capabilities compared with Aluminum Nitride (AlN) and Alumina (Al2O3). These properties makes BeO ceramic a great candidate for the moderator/reflector materials in nuclear reactors. It is also widely used in medical, industrial and electronics industries.
