In the modern industries, advanced ceramic component is very commonly used in many, many electron vacuum devices, like electron tubes, high voltage feedthru, high current feedthru, vacuum interrupter, vacuum capacitors/Thyristors, X-ray tubes and power switches and so on.
The key point is what a metal coating covers on the surface of ceramic body, or ceramic base to achieve the vacuum hermetical and sealing, such as nickle plating, sliver plating, gold plating, copper plating and Tin plating. The main features for vacuum ceramic component as below:
-Extremely high bond/brazing strengths
-High mechanical strength
-Minimum electric resistance and vacuum tightness
-Excellent insulation
The typical form for vacuum ceramic component is to be as an insulator, ceramic packaging and ceramic body etc.
