[Solution Case] Development of Sintered Bodies of Conductive Ceramics and Metals

Considering the required characteristics as appropriate, optimize the selection of raw materials, mixing, and sintering conditions for development and manufacturing.

Alumina ceramics cannot be sealed using a bonding method like glass, so instead, a method is generally employed where frit glass is melted and poured into the small gap between the electrode and the valve to seal it. Therefore, the electrode materials in the sealing area require conductivity, high-temperature resistance, and halogen resistance, and it is also necessary to ensure that there is an appropriate thermal expansion coefficient relationship between the frit glass, alumina valve, and electrode. Considering the required characteristics of alumina powder and Mo powder (or W powder), the selection of raw materials, mixing, and sintering conditions are optimized to develop and manufacture conductive materials. When the melted frit glass flows into the small gap (capillary) due to capillary action, factors such as the surface roughness of the developed materials are also taken into account, and processes like centerless grinding are performed for finishing. *For more details, please refer to the external link page or feel free to contact us.*
