Electric vacuum ceramic is the mainly components of high-voltage electric vacuum ceramic tube,high-power silicon controlled rectifier, electric vacuum relay, electric vacuum transmitting tube, High-frequency high power electric tube. We use the best 95% alumina with superfine powder technology and isostatic pressing : Steady performance, Good insulating.The sizes can be made strictly according to the customers' requirements , with Metallization and glazing on the surface.

Features: 

1.Good density ,low dielectric loss and Dielectric Constant with small crystal size (Average diameter 8~10μm ). The structure density is far exceeded than the traditional forming technology through hundreds Mpa pressure

2. No air holes. There is no air holes in the ceramic parts through isostatic pressing technology. The inside structure and tensile strength reach the best condition

3. High mechanical strength, High sealing strength, Good air tightness, which highly improves the tightness of the electric vacuum ceramic tube

4. Good consistency, The mainly technical indexes of the electric vacuum ceramic have reached the advanced level of same sort products at home and abroad
