Product Description

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 seal joints of superb bonding strength and hermeticity are required.

Our facility specializes in molybdenum/tungsten thick film metallization on 95% alumina ceramics. Also, we metallized high purity alumina, like 99% alumina, zirconia and beryllia. 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 selective of metallization type as following:

●Ceramic body + Mo/Mn metallization.........................................................................................Ceramic body + silver plating

Ceramic body + tin plating........................................................................................................Ceramic body + W metallization + Gold plating

Ceramic body + Mo/Mn metallization + Nickle plating

We are capable of doing high precision process, like fine grinding and CNC machining to meet strict dimensional requirement. Also we are able to do glazingMetallized Ceramic Cylinder
