The key preparation processes of barium tungsten electrode include porous tungsten matrix, barium impregnation reduction, etc. The following is its main process flow:

I. Preparation of Porous Tungsten Matrix

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.

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.
