What is the use of Vacuum Ceramic Tube?

Vacuum Ceramic Tube is widely used as vacuum tube shell material due to its advantages of good insulation, high strength, abundant raw material sources and low cost.

When Vacuum Ceramic Tube is used as the shell for vacuum tube, its end face must be metallized so that it can be sealed with other components to form a sealed container to meet its performance requirements. In order to obtain end-face metallized ceramic vacuum tubes with good performance, various ceramic metallization methods have been proposed successively, such as vacuum ion plating, vacuum evaporation, magnetron sputtering, sintered metal, sintered metal powder and uniform precipitation, electroplating, chemical plating, etc. .
