| titleOfInvention | Method for producing colloidal silica |
| abstract | The present invention discloses a method for producing a colloidal silica using silicon metal as a raw material, which enables to produce a colloidal silica having high concentration and low viscosity. Also disclosed a method for producing a colloidal silica using silicon metal as a raw material, which enables to produce a colloidal silica in short time with high yield without comprising a concentration step. Further disclosed is a method for producing a colloidal silica, which enables to easily control the particle size of silica contained in a colloidal silica. Specifically disclosed is a method for producing a colloidal silica comprising a step for obtaining a colloidal silica by reacting silicon metal (Si) with water in an aqueous solution containing an alkaline catalyst and a dispersing agent, wherein the dispersing agent is composed of one or more ionic substances selected from inorganic acids, organic acids and their salts. Also specifically disclosed is a method for producing a colloidal silica comprising a step for controlling the particle size of silica by adjusting the addition rate of silicon metal into an aqueous solution containing an alkaline catalyst and a dispersing agent. |
