High-Current Hermetic Ceramic Feedthrough For CO₂ Laser Power Systems

Ceramics possess the properties of heat resistance, insulation, wear resistance and corrosion resistance. They are suitable for use in high-temperature, vacuum and corrosive environments and are widely applied in semiconductors, optoelectronics and various industrial equipment. However, they cannot independently perform load-bearing, conductive and sealing operations and...

What Is Ceramic Vacuum Feedthrough? The ceramic vacuum feedthrough is a ceramic to metal seals components, it is a ‘feedthrough’ hermetic connector that allows electrical power, signals, motion, or fluids to safely pass through the wall of a vacuum chamber. It uses 95% alumina ceramic as an insulator to achieve vacuum sealing, and is a critical component in many vacuum...

In oil and gas drilling, shale gas fracturing, and offshore platform operations, the mud pumps have to operate continuously under high pressure and large flow conditions throughout the year. The drilling fluid contains a large amount of hard impurities such as rock chips and sand grains. When flowing at high speed, it will constantly wash and wear the inner wall of the c...
