Beryllium Oxide (BeO) ceramics are high-performance advanced materials that combine exceptional thermal, electrical, and mechanical properties. With a thermal conductivity of 200–325 W/m·K—more than ten times that of alumina—BeO efficiently dissipates heat from high-power devices. It offers a high melting point of 2530±10°C, excellent electrical insulation, low dielectric constant (~6.7), and ultra-low dielectric loss (<0.0004), making it ideal for both high-power and high-frequency applications. Its coefficient of thermal expansion closely matches silicon, ensuring reliable performance under thermal cycling.
BeO ceramics are widely used in:
Microwave & RF electronics: traveling wave tubes, klystrons, high-power amplifiers, radar systems
Power semiconductors: IGBT modules, GaN/SiC device packaging
