Product Description

Pink Ceramic Metallization Alumina Insulator for New Energy Application

With the new energy industry development, technical metallized ceramic components have widely used in the application between ceramic to metal, ceramic to ceramic jointing because of its outstanding properties. We commonly utilize thick and thin-film technologies in our refractory metallising, depositing proprietary coating to our ceramic components according to different customers' specifications.

All these ceramic metallization insulator have a superb bonding strength, extremely low leak rate. They can be bonded with Kovar alloy, copper and stainless steel directly by means of brazing.

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
