High Voltage Vacuum Ceramic Tube for Electron Tube

We supply a variety of custom refractory Metallized alumina ceramics for use in vacuum interrupters, power grid tubes, x-ray tubes and similar applications where ceramic-to-metal, ceramic to ceramic sealing joints of superb bonding strength and hermeticity are required.

Our facility specializes in molybdenum/tungsten thick film metallization on high purity Alumina Ceramic components. Also, we are capable of dealing with metalized zirconia ceramic parts and metalized beryllia ceramics . We utilize electro or electroless nickel/silver/gold plating as the preferred deposition over metallization. The result in a system easily brazed with cooper-silver, pure cooper, gold and other common braze alloys.

We have a selection of metallization type as following:

●Ceramic body + Mo/Mn plating............................................................●Ceramic body + Silver plating

●Ceramic body + Tin plating..................................................................●Ceramic body + W metallization + Gold plating

●Ceramic body + Mo/Mn metallization + Nickle plating

Sometimes, in order to achieve precision fitting relationship, precision grinding and CNC machining are needed to performed, all these precision processing can be done at house. Furthermore, we owns our glazing process line to meet the glaze needs in the application.
