BeO (Beryllium Oxide) Ceramic Substrates

Beryllium oxide, BeO ceramic substrates have 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 ceramics has no analogues among oxide-ceramic materials in terms of thermal conductivity. BeO-based ceramics have 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 aluminum nitride, therefore BeO is an excellent insulator with a volume resistance of the order of 1014...1018 Ohm∙cm, which depends on the purity of the material. In addition to high heat resistance, BeO has excellent strength with high values of specific hardness. Beryllium oxide BeO2 ceramic substrates can be used as boards for electronic devices operating with microwave radiation, substrates for solid-state emitters; X-Ray ICs, housings for heating elements; substrate for sensors of ionizing radiation.
