Beryllium Oxide (BeO) parts

Beryllium oxide [BeO] has a unique combination of thermal, electrical, optical and mechanical properties that are used for a wide range of applications: from thermal control systems and integrated electronics to high-temperature refractory components and nuclear reactors. Beryllium oxide has no analogues among oxide-ceramic materials in terms of thermal conductivity.

BeO-based ceramics have a thermal conductivity exceeding that of many metals, second only to copper and silver. At the same time, the thermal conductivity of BeO is 10 times higher than that of Al2O3, and 1.5 times higher than that of AlN.

The dielectric constant is lower than that of aluminum oxide and nitride. In this connection, BeO is an excellent insulator with a volumetric resistance of the order of 1014 ... 1018 ohms * cm, which depends on the purity of the material.

In addition to high heat resistance, BeO has excellent strength with high values of specific stiffness.

Ceramics based on beryllium oxide BeO are produced according to TU23.43.10-008-34576770-2017 under the trademarks OBK-97 and OBK-100.
