As a high-performance electrode material, the core advantages of barium tungsten electrode are reflected in the following four aspects:

Barium tungsten electrode is a cathode material widely used in electron tubes and gas discharge tubes. It occupies an important position in related fields due to its unique properties.

As a commonly used cathode material, although barium tungsten electrode is widely used in electron tubes and gas discharge tubes, it also has some significant disadvantages. In practical applications, it is necessary to weigh its advantages and disadvantages according to specific needs, and consider technical improvements or alternative materials to make up for these shortcomings.

The barium tungsten electrode is a highly efficient thermionic electron emission cathode. Its working principle is based on the reduction of the work function of the tungsten substrate surface by the active substance of barium, thereby significantly improving the electron emission efficiency. The following is a detailed analysis of its working principle:
