The bombardment-resistant barium tungsten electrode is mainly made of a composite material of tungsten (W) and barium (Ba). Tungsten is a metal with a high melting point (over 3400°C) and high hardness, so it is very suitable as an electrode material because it can maintain stability under high temperature and high pressure.
In the bombardment-resistant barium tungsten electrode, barium is usually introduced into the tungsten matrix as an electron emission material. Barium compounds (such as barium oxide or barium aluminate) are coated on the tungsten matrix and react with tungsten at high temperature to form barium tungsten compounds. This compound has a low work function, that is, it can emit electrons under a low electric field, thereby improving the electron emission performance of the electrode.
The bombardment-resistant barium tungsten electrode may also contain other additives, such as aluminum oxide (Al2O3), etc., to improve the stability, mechanical strength or corrosion resistance of the electrode.
In short, the bombardment-resistant barium tungsten electrode is a composite material composed of tungsten and barium as the main components, with excellent electron emission performance and stability, and is widely used in gas discharge lamps, laser devices, light source equipment and other fields.
