Barium tungsten electrode (usually refers to tungsten-based cathode impregnated with barium salt) is widely used in high-power microwave tubes, high-pressure gas discharge lamps, plasma sources and other equipment that require high temperature and high pressure environment due to its excellent electron emission ability and certain high temperature resistance. Its high temperature and high pressure adaptability is subject to the interaction of multiple complex influencing factors, which can be mainly summarized as follows:

Barium tungsten electrode is an important cathode material, widely used in vacuum electronic devices such as microwave tubes, X-ray tubes, etc. Its preparation cost factors include raw materials, energy, equipment, labor, production efficiency and scrap rate.

Surface contamination control of barium tungsten electrode requires comprehensive management from multiple dimensions such as material design, process optimization, environmental management, operating specifications, and use conditions. By accurately controlling the barium tungsten ratio, optimizing the preparation process, maintaining a high vacuum/inert environment, strictly following operating specifications, and reasonably selecting electrical parameters, the electrode's anti-pollution ability and service life can be significantly improved.

As a typical product made from the refractory metal molybdenum (Mo), molybdenum bar is a rod - shaped item with molybdenum as its primary raw material. Therefore, it is often referred to as a molybdenum rod or molybdenum stick. In English, it is known as "molybdenum bar" or "molybdenum rod." With a purity of up to 99.7%, it is widely used in metallurgy, power equipment, and other fields due to its excellent thermal, mechanical, chemical, and electrical properties.
