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
Nuclear technology: neutron reflectors, moderators, and control rod components
Optoelectronics: laser diode substrates, high-power LED packages
Aerospace & defense: hermetic packages and heat-dissipating substrates
Alumina (Al₂O₃) is the most widely used advanced ceramic material, offering exceptional mechanical strength, electrical insulation, thermal stability, and corrosion resistance.
Coraynic Technology Limited provides four purity grades—A-95, A-97, A-99, and A-99.8—tailored to diverse applications. A-95 offers good mechanical properties and thermal shock resistance for precision parts. A-97 provides excellent chemical stability and high breakdown strength. A-99 delivers the highest performance with 455 MPa flexural strength and 54 kV/mm breakdown strength.
Key Properties:
Density: 3.80–3.91 g/cm³
Flexural strength: 385–455 MPa
Breakdown strength: 38–54 kV/mm
Volume resistivity: >10¹⁴ Ω·cm
Air impermeability: <5.0×10⁻¹² Pa·m³/s
Metallization & Sealing: We offer proprietary metallization (minimum hole diameter 0.2 mm) and ceramic-to-metal sealing via brazing, electron beam, and laser welding, ensuring strong bonding force, excellent solderability, and hermeticity.
Applications: Power modules, automotive electronics, aerospace components, medical devices, industrial wear parts, LED heat sinks, substrates, and chemical catalyst carriers.
