The ceramic tubes which have glazed surface can apply with the quite harsh environment

 because they have good  moisture preventing ability and insulating ability.

 

Applications:high voltage relays,vacuum switching tubes,vacuum capacitors

Metallized ceramic can be application in the production of porcelain controls,

 surge arresters, surge arrester with insulation, high temperature resistance, 

good air tightness, fast heat dissipation, high mechanical strength and high stability 

high voltage relays,vacuum switching tubes,vacuum capacitor in harsh working environment, good soldering and solder with gold, silver, copper, nickel and so on.
