Barium tungsten cathode is a composite material consisting of barium oxide and tungsten, providing a stable electron source or photoelectron source for electronic devices.
How to produce barium tungsten cathode? The following processes are their regular steps.
Raw material preparation: purchase high-quality tungsten powder and barium compound to ensure that the raw materials meet the production requirements.
Mixing and grinding: according to the specific formula ratio, mix tungsten powder and barium compound, and put the mixture into a ball mill for grinding to obtain a uniform mixed powder.
Pressing: put the ground mixed powder into a mold and perform high-pressure pressing to shape it into a cathode of the desired shape.
Sintering: put the pressed cathode into a high temperature furnace for sintering. At high temperatures, tungsten and barium compounds react to form a barium-tungsten composite, forming a strong cathode structure.
Tungsten cathode treatment: after sintering, the cathode may need some subsequent treatment, such as cutting, grinding, polishing, etc., to ensure that the size and surface quality of the cathode meet the requirements.
Soldering: in some special applications, the cathode may need to be welded to other components to assemble a complete electronic device.
Inspection and testing: quality inspection and performance testing are carried out on the finished barium tungsten cathodes to ensure that they meet the specified technical requirements and standards.
Packaging and delivery: qualified finished cathodes are packaged to prevent damage during transportation and are ready for delivery.
It should be noted that the production process involves high temperature and chemical reaction, and it should be strictly followed the relevant safety operation rules to ensure the safety and stability of the production process. In addition, the preparing methods may vary by manufacturer and product type.
