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.

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

1. Material Composition

As a typical product of the transition metal molybdenum, a molybdenum boat, also known as an evaporation molybdenum boat or coating molybdenum boat, is made from molybdenum sheets or molybdenum-based alloys through welding or high-temperature stamping. It serves as a critical sintering carrier for molybdenum powder and other metal powders, with its English name being "molybdenum boat".
