The metal oxide compound impregnated barium tungsten cathode is a special cathode material, the main feature of which is that the metal oxide compound is impregnated into the base material of the barium tungsten cathode through a specific process.
This cathode material combines the specific properties of metal oxide compounds and the advantages of barium tungsten cathodes. Metal oxides, such as aluminum oxide, barium oxide, etc., have unique physical and chemical properties, such as high melting point, good electron conductivity and stability. Barium tungsten cathodes are known for their excellent electron emission performance.
Through the impregnation process, metal oxide compounds can be evenly distributed in the base material of the barium tungsten cathode to form a stable composite structure. This composite structure can further enhance the electron emission performance of the cathode and improve its stability and life.
The metal oxide compound impregnated barium tungsten cathode is widely used in electron tubes, vacuum tubes and other equipment that requires stable electron emission. It can improve the performance and reliability of the equipment and extend its service life.
