Barium tungsten electrodes are mainly used for certain specific applications, such as plasma welding or discharge machining, and their burnout rate (the loss rate of electrode materials caused by high temperature, arc or other factors during operation) is affected by many factors. The following are the main factors affecting the burnout rate of barium tungsten electrodes:

The factors affecting the surface roughness of barium tungsten electrodes involve multiple links such as material preparation, working environment, processing technology and post-treatment, and their formation mechanism is complex and interrelated.

The emission efficiency of barium tungsten electrodes is the result of the coupling of multiple influencing factors, mainly involving material properties, preparation process, working conditions and environment, etc.

The thermal expansion coefficient of barium tungsten electrode is mainly affected by factors such as material composition (ratio of barium to tungsten, doping elements), microstructure (grain size, porosity), preparation process (sintering, pressing, heat treatment) and use environment (temperature, atmosphere).
