Barium tungsten electrode may be used as an efficient electron emission source in night vision equipment, and the photoelectric conversion efficiency is improved by combining the low work function of barium with the stability of tungsten. Its application is mostly seen in traditional or special night vision equipment, especially in scenes that require high current density or specific infrared response.

The barium tungsten electrode used in electropulse sterilization equipment is a high-performance electrode material. Its core advantages lie in the combination of tungsten's high melting point, corrosion resistance, and barium's low work function characteristics.

Barium tungsten electrodes, owing to their unique physicochemical properties, demonstrate extensive application potential in plasma generation devices. As a core electron emission source, their low work function and high current density characteristics provide critical support for the diversified applications of plasma technology.

In plasma equipment, barium tungsten electrodes are frequently used as cathode materials due to their superior electron emission properties and high-temperature resistance. Below is a concise overview of the applications of barium tungsten electrodes in plasma equipment:
