The application of barium tungsten electrodes in electric vacuum devices is mainly reflected in the following aspects:
Electro-light source products
Barium tungsten electrodes have low work function and high electron emission ability, which makes them an ideal electrode material in electric light source products. In electric light source products, tungsten, as a high melting point metal, shows good stability and corrosion resistance, while barium can improve the conductivity of the electrode. Therefore, the electron emission performance of barium tungsten electrodes can reach a repetition frequency from low to high (1~40 times/second), which is suitable for various electric light source products, such as strobe lights.
Laser devices
In laser devices, barium tungsten electrodes also play a key role. Its excellent electrochemical properties and stability enable laser devices to work stably and efficiently. In addition, barium tungsten electrodes can also improve the starting performance and energy conversion efficiency of laser devices.
Electro-vacuum devices
Barium tungsten electrodes are common electrode materials in electric vacuum devices. Due to the high melting point and stability of tungsten and the conductivity of barium, barium tungsten electrodes can maintain stable performance in an electric vacuum environment and withstand higher voltages and currents. This makes it widely used in various electric vacuum devices, such as vacuum tubes, electron beam tubes, etc.
Medical positioning therapy light source
In the medical field, barium tungsten electrodes are also used to prepare medical positioning therapy light sources. This light source has high brightness, stability and precise positioning capabilities, which can meet the needs of medical diagnosis and treatment.
