Large Size Alumina Metallized Ceramic Cylinders for Vacuum Interrupter
The description of metalized ceramic cylinders
Metallized Ceramic Cylinders are commonly used in high voltage, high current electrical, electronic applications.
In order to achieve the jointing from metal to ceramics, a metallic layer will be applied on a certain surface of ceramic insulators with high-temperature sintering.
The metalized alumina ceramic components we manufactured are famous for excellent bonding strengthen, super mechanical, excellent electrical insulation, exceptional thermal features.
Jointing types of metalized ceramic cylinders
1.Alumina ceramic base + Ag plating
2.Alumina ceramic base + Mo/Mn metallization
3.Alumina ceramic base + Mo/Mn metallization + Ni plating
4. Alumina ceramic base + Tungsten metalized + Au plating
The cosmetic quality of metalized ceramics
1. The flatness of both end sides must be less than 0,01mm
2.No blister on nickel ( outer) plating at the temperature up to 1150°C
3.No any crack on the surface
4.No any dark spot ( impurities) on the external surface
5.With evenly glaze distribution
The application of metalized ceramics
Electron tubes, Vacuum interrupters, Vacuum electrical breakers, Surge arresters,X-ray tubes and so on.
