Impregnated barium tungsten cathode solder is a special material used to prepare impregnated barium tungsten cathode. It is mainly composed of palladium powder, tungsten powder and cobalt powder mixed in a certain proportion, and the purity of these powders is usually required to be between 95-100%. The ratio of the solder can be expressed as the weight ratio of palladium powder, tungsten powder and cobalt powder converted to 100% purity is 1:5-40:10-90.
The use method of impregnated barium tungsten cathode solder usually includes material annealing, grinding, pressing, welding, salt immersion and other processes. Through these steps, the solder can form an impregnated barium tungsten cathode with excellent electron emission performance.
Impregnated barium tungsten cathode material is widely used in various microwave devices, especially high-power microwave devices. Compared with traditional cathode materials, impregnated barium tungsten cathode has the advantages of firm welding, low vapor pressure, long service life and good stability. It can adapt to various complex weather and terrain conditions, especially in applications such as multi-injection microwave tubes.
