Beryllia / Beryllium Oxide (BeO)

Beryllium oxide (BeO), also known as beryllia, is an inorganic compound that is a white crystalline solid and has a unique combination of thermal, electrical, optical, and mechanical properties. Beryllia is an electrical insulator and an excellent thermal conductor, with conductivity higher than any other non-metal except diamond and many metals. It is an ideal material for applications requiring large heat dissipation and dielectric and mechanical strength. Beryllia’s high melting point leads to its use as a refractory material.

Note: Beryllium oxide is toxic; beryllium oxide ceramics are not toxic.

Available purity 99.5%, 99.7%, and 99.98% trace metals basis
Typical Applications

Beryllium oxide is used in the fields of special metallurgy, vacuum electronic technology, nuclear technology, microelectronics, and photoelectron technology. It has a diverse range of applications from thermal management systems for integrated electronics to high-temperature high-performance refractory components for nuclear reactors.
