The reserve type barium tungsten electrode is a high-performance hot cathode composed of a porous tungsten matrix and electron emitting materials filled in it. It has the advantages of low escape work, low operating temperature, and high emission efficiency. Its applications are mainly concentrated in the following areas:
Xenon flash lamp field
Reserve barium tungsten electrode is the core material of xenon flash lamps, widely used in professional photography, intelligent transportation, laser beauty, laser pumping, nuclear power and other fields. These flash products include photography lights, electronic checkpoint lights, skin rejuvenation and hair removal beauty lights, solar detection, pump light source lights, pulse sterilization, industrial counting lights, indicator lights, and signal lights.
Electrochemical analysis and solution electrolysis
Barium tungsten electrodes are widely used for electrochemical analysis of halogen elements, heavy metal ions, and drugs in aqueous solutions due to their excellent electrochemical properties, such as high stability and low capacitance.
Optoelectronic products
Barium tungsten electrodes have excellent characteristics such as high electron emission ability, low escape work, high electron emission current density, good gas discharge lamp ignition speed, and low electrode operating temperature. Therefore, they are also widely used in optoelectronic products, such as HID lamps.
Other fields
Due to its advantages of no radioactive toxicity and anti poisoning ability, barium tungsten electrodes are also used in fields such as navigation mark identification, target tracking, stage and dance hall effect display, film and television projection and recording, medical positioning and treatment light sources, and military weapons.
The specific uses of barium tungsten electrodes may vary depending on the application field and specific needs. Therefore, when selecting and using barium tungsten electrodes, it is necessary to evaluate and choose according to specific circumstances.
