Ceramic Shell for High Voltage Vacuum Switching Relay

Ceramic shell in vacuum switching relay is one of insulating part. It's commonly made from Alumina Ceramic with exceptional electrical dielectric strength. As the vacuum switch relay will related to metal to ceramic parts jointing, then a metallizing layer (Molybdenum or tungsten) will be applied on the certain section of the ceramic body to achieve the brazing together purpose. In order to prevent the metallization layer into oxidizing, an addtional metallic coating will be covered on the metallization one, mainly including nickle, gold plating.

We focus on Metalized Ceramic Insulator over for 10 years, and deeply learn the know-how to ensure the brazing strength between metal and ceramics, how to guarantee the air tightness in the application.
