Beryllium Oxide Ceramic Description:
Beryllium oxide ceramic is a high-performance technical ceramic material primarily composed of high-purity beryllium oxide (BeO). It combines the high thermal conductivity of metals with the excellent electrical insulation properties of ceramics, while also possessing good high-temperature resistance, chemical stability, and mechanical strength. It is an indispensable functional ceramic material in the electronics, power, and high-end industrial sectors.
Types of Beryllium Oxide Ceramics:
Beryllium Oxide Ceramic Substrate/BeO Ceramic Substrate
Beryllium Oxide Ceramic Plate/BeO Ceramic Plate
Custom-made structural components (manufactured according to drawings)
Beryllium Oxide Ceramics Features:
1. Ultra-high thermal conductivity
Thermal conductivity can reach 200-330 W/m·K, approaching or even exceeding that of some metals, and far higher than that of alumina ceramics.
2. Excellent electrical insulation properties
Maintains stable electrical insulation even in high-temperature and high-frequency environments.
3. Good high-temperature resistance
Melting point is approximately 2530°C, making it suitable for high-temperature applications.
4. Good mechanical strength and wear resistance
High compressive strength and good dimensional stability.
5. Strong chemical stability
Resistant to acid and alkali corrosion, and maintains stable performance in various chemical environments.
6. Low dielectric constant and low dielectric loss
Very suitable for high-frequency, high-speed electronic applications.
