[Solution Case] Manufacturing of Emitter-Impregnated Porous W Electrodes

Conducting genuine trial and error with agility! Our approach to development.

To achieve low-energy discharge, the electrodes must be made of materials with a low work function. One method is to add oxides and manufacture them through sintering; however, if there are too many oxides, the sintering temperature for tungsten may differ, which can result in insufficient sintering conditions. In such cases, tungsten alone can meet the necessary sintering conditions and maintain its physical properties at a high level. Subsequently, emitters that have been manufactured separately and can add easy discharge properties are impregnated into the sintered tungsten, ultimately resulting in a state where both are physically and chemically bonded. To realize this, hundreds or thousands of patterns must be repeatedly experimented with and developed. This diligent trial-and-error approach, carried out with agility, is the attitude and characteristic of our company's development efforts. *For more details, please refer to the external link page or feel free to contact us.*
