Ceramic Insulator for Switch Ignitor Discharge Tube

Ceramic Insulator for Switch Igniter Discharge Tube

Ceramic insulator for switch igniter discharge tube is made of alumina oxides with min. 95% purity, It can be shaped via dry pressing,  hot pressing, ISO pressing. In common case,  both molybdenum-manganese and Tungsten as a very popular metallizing paste are to be plated on certain surface of ceramic body via banding, screen printing, brushing, spraying to meet the brazing usage between metal and ceramic.

The ceramic metallized body have a very good bonding strength with ideal airtightness at ceramic to metal jointing technology.

Prime features of Metalized Ceramics:

● Excellent bonding strength to be 150MPa/mm2 with ideal leakage rate ● Dense, non-porous and vacuum tight    

● High volume resistivity and insulation breakdown to be 20KV/mm at least● Low coefficient of expansion

● Resists chemical attack and can wit                                                 ●Fire resistant and non-outgassing

● Readily accepts Mo/Mn or W metallizing for high temperature brazing of variety of metal to ceramic assemblies           

With their exceptional properties on mechnical, electrical and thermal. These Vacuum Ceramic Component are widely used in vacuum interrupters , Electron tubes,Gas discharge tube, vacuum capacitor,Vacuum thyristorsSurge arresters ,Thyristor housings,diode housings ,Power grid tubes, Traveling wave tubes,Insulator rings and cylinder ,X-ray tubes and a various of vacuum devices based on interrupter application.
