Impregnated barium tungsten electrodes have the following significant characteristics:
High electron emission performance
The impregnated barium tungsten electrode significantly improves the electron emission ability of the electrode by impregnating barium or other active substances. This enables it to emit electrons quickly and stably in applications such as gas discharge lamps and high-frequency strobe lamps, ensuring the normal operation and efficient operation of the equipment.
Low work function
The work function is the minimum energy required for electrons to escape from the surface of a solid. The lower work function of the impregnated barium tungsten electrode means that under the same conditions, the electrode can emit electrons more easily, further improving its electron emission performance.
High electron emission current density
The impregnated barium tungsten electrode is able to produce a higher electron emission current density over a smaller area. This gives the electrode a clear advantage in miniaturized, high-power density equipment.
Good gas discharge lamp ignition speed
In gas discharge lamps, the impregnated barium tungsten electrode can start quickly and work stably to achieve fast ignition. This helps to improve the response speed and stability of the equipment.
Low electrode operating temperature
The impregnated barium tungsten electrode generates less heat when working, so the operating temperature of the electrode is relatively low. This helps to extend the service life of the electrode and reduce the energy consumption of the equipment.
High stability and durability
The impregnated barium tungsten electrode has good chemical and physical stability, and can operate stably for a long time in harsh working environments. At the same time, it has high mechanical strength and can resist erosion and damage from the external environment.
Wide range of application fields
Due to the above excellent characteristics of the impregnated barium tungsten electrode, it is widely used in gas discharge lamps, high-frequency strobe lamps, microwave devices and other fields. These devices play an important role in medical, scientific research, industry and other fields.
