The advantages of barium tungsten electrode are mainly reflected in the following aspects:
High electron emission ability
The barium tungsten electrode significantly improves the electron emission ability of pure tungsten electrode through alloying treatment. This improvement increases the electron generation and electron current density, thereby improving the ignition speed of gas discharge lamps, enabling the lamps to start at a lower voltage and maintain stable brightness.
Excellent electrochemical properties
The barium tungsten electrode exhibits electrochemical properties such as high stability and low capacitance, making it very sensitive to the redox response of various organic and inorganic substances. This makes it widely used in the field of electrochemical analysis, such as the detection of samples such as halogen elements, heavy metal ions and drugs in aqueous solutions.
Good corrosion resistance and thermal stability
The barium tungsten electrode can work under a wide range of pH conditions and has high corrosion resistance and thermal stability. This allows it to maintain stable performance even under harsh environmental conditions and prolongs the service life of the electrode.
Suitable for high-intensity gas discharge lamps
The barium tungsten electrode is an ideal electrode material for high-intensity gas discharge lamps such as xenon flash lamps. Its high electron emission capability enables xenon flash lamps to have higher flash rates and greater brightness, and can be used normally in environments with voltages lower than the mains supply, thus improving the efficiency and reliability of lamps.
