Barium tungsten electrode is a special electrode material widely used in electronic tubes, gas discharge lamps and other equipment. Its physical properties are the key to its performance and application. The following are the main physical properties of barium tungsten electrode:

Barium tungsten electrode is a material widely used in electron tube cathodes, and is valued for its good emission performance and stability. The manufacturing process of barium tungsten electrode is mainly based on the impregnation method, which can effectively avoid the problems of barium volatilization and uneven distribution that may be caused by direct mixed sintering. It is a relatively mature and commonly used process.

Barium tungsten electrode (BaO-W electrode) is a key electrode material used in gas discharge lamps (such as high-pressure sodium lamps and metal halide lamps). Its production steps are as follows:

The preparation of barium tungsten electrode by impregnation is a process commonly used in electron emission materials (such as hot cathodes). By impregnating active barium compounds into porous tungsten substrates, composite electrodes with high-efficiency electron emission performance are formed. The following is a detailed preparation process and key points:
