Beryllia / Beryllium Oxide (BeO) Description:

Beryllium oxide (BeO), also known as beryllia, is an inorganic compound with the formula BeO. This white crystalline solid is notable as it is an electrical insulator with a thermal conductivity higher than any other non-metal except diamond, and actually exceeds that of some metals. Its high melting point leads to its use as a refractory. It occurs in nature as the mineral bromellite. Historically beryllium oxide was called glucina or glucinium oxide.

Beryllia / Beryllium Oxide (BeO) Typical Applications:

"Beryllia is the best ceramic thermal conductor and competes with the most conductive metals (see beryllium oxide properties and beryllium oxide thermal conductivity). Electrical isolation is equivalent to that of alumina and the best electrical insulators. A 20% lower dielectric constant than alumina and aluminum nitride offers advantages in the high-frequency field. Its high chemical and temperature stability in harsh environments has been proven in over sixty years of service."
