We supply a number of many custom refractory metallized alumina ceramic isolators for use in gas discharge tubes, high current feedthrus, 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 copper-silver, pure copper, gold and other common braze alloys.
Metallization types:
● Ceramic body + Silver (Ag) plating
● Ceramic body + Molybdenum-Manganese ( Mo-Mn) metallization
● Ceramic body + Molybdenum-Manganese ( Mo-Mn) metallization + Nickle ( Ni ) plating
● Ceramic body + Tungsten ( W ) metallization + Gold ( Au ) plating
Special types are available according to customer's drawings or samples
Main characteristics of Metallized ceramic isolator
● Min. electric resistance and vacuum tightness, and less than 1×10-11 Pa•m3 / s
● High bonding/brazing strength, It can be up to 150 MPa after brazing
● High mechanical strength, flexural strength can be up to 338 MPa
● High insulation, anti-chemical and anti-aging. It will be free of rust forever
Applications:
Vacuum interrupters, Vacuum circuit breakers, Feed-through insulators, Headers, High-power receptacles, Insulating discs, Insulator rings and cylinders, Precipitator products, Power switches, Traveling wave tubes, Windows, Power grid tubes, X-ray tubes
