ceramic metallized vacuum electrode is designed to withstand high temperatures, vacuum conditions, and corrosive environments. It is commonly used in vacuum tubes, electron guns, plasma processing equipment, and other high-tech devices that require precise control of electron or ion beams.

The metallized coating on the ceramic electrode helps to create a strong bond between the metal and ceramic materials, ensuring reliable performance over extended periods of use. This type of electrode is also known for its high thermal conductivity, which allows for efficient heat dissipation and prevents overheating.

The flange design of the electrode allows for easy installation and removal from the vacuum system, making it convenient for maintenance and replacement. The alumina material ensures long-term reliability and durability, even in harsh operating conditions.

the alumina vacuum ceramic flange electrode is a versatile and reliable component for various vacuum system applications, providing stable and efficient electrical performance for extended periods of time.

Our metallizing processes could be customized according to clients’ requirements.

The vacuum electrode flange is usually composed of the following structures:
1. Contact: used to connect two flanges, usually made of copper or stainless steel.
2. Flange: a flat plate mounted on the contact, between which a vacuum sealing chamber is formed.
3. Bolts: Components for fixing and connecting flanges.
4, insulation gasket: the insulation material installed between the bolt and the flange to ensure the insulation performance of the flange.
5, conductive plug: used for grounding at non-standard connections to ensure the electrical safety of the system.
