The application of barium tungsten electrode in high-frequency plasma benefits from its unique material properties: tungsten provides stability and heat resistance, and barium reduces the work function to improve the electron emission ability. This electrode is an efficient electron emission source in high-frequency plasma systems, which can help generate and maintain stable plasma and is widely used in material processing, surface treatment and plasma chemistry.

The thermal cycle performance of barium tungsten electrodes refers to their ability to maintain structural integrity and performance stability during repeated heating and cooling. The main influencing factors are as follows:

The realization of the machining accuracy of barium tungsten electrodes requires comprehensive control of multiple influencing factors such as material properties, machining parameters, environmental conditions, operating skills and quality inspection.

Barium tungsten electrode (usually refers to tungsten-based cathode impregnated with barium salt) is widely used in high-power microwave tubes, high-pressure gas discharge lamps, plasma sources and other equipment that require high temperature and high pressure environment due to its excellent electron emission ability and certain high temperature resistance. Its high temperature and high pressure adaptability is subject to the interaction of multiple complex influencing factors, which can be mainly summarized as follows:
