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 glazing and polishing finish by ourselves.Metallized Ceramic Cylinder
