Abstract
A method for producing an anode body in a capacitor, which includes making a molded body by molding a tungsten powder and making an anode body by sintering the molded body, which includes a step of bringing the tungsten powder or the molded body thereof into contact with a solution of a silicon compound before sintering the molded body so as to adjust the silicon content in the anode body to 0.05 to 7 mass %.
Claims16
A method for producing an anode body in a capacitor,
- comprising making a molded body by molding a tungsten powder
- and making an anode body by sintering the molded body,
- which comprises a step of bringing the tungsten powder or the molded body thereof into contact with a solution of a silicon compound before sintering the molded body so as to adjust the silicon content in the anode body to 0.05 to 7 mass %.
A method for producing a tungsten granulated powder, comprising a process of bringing a raw material tungsten powder into contact with a solution of a silicon compound, and a process of pulverizing the tungsten powder after the calcination of the raw material tungsten powder treated with a solution of a silicon compound.
