The mechanical strength of barium tungsten electrodes is the result of the combined effects of material composition, microstructure, preparation process and working environment. To improve the strength, the barium content can be optimized, the grain size can be controlled, the sintering process can be improved, the internal defects can be reduced, and the surface quality can be ensured. In practical applications, each influencing factor needs to be weighed according to the specific conditions of use.

The factors affecting the long-term stability of barium tungsten electrodes and their mechanisms of action are as follows:

1. Material Composition

The factors affecting the surface active substances of barium tungsten electrodes can be comprehensively analyzed from multiple dimensions such as material composition, preparation process, working environment, surface treatment, impurity pollution and use time, as follows:

The surface energy of barium tungsten electrode is affected by many factors such as intrinsic properties of the material (such as barium content, crystal structure), surface state (roughness, oxide layer), environmental conditions (temperature, vacuum degree) and preparation process (heat treatment, surface modification). In practical applications, optimizing these influencing factors can improve the electron emission performance and stability of the electrode.
