| description | A method for producing solid particles having a silica coating, by: dispersing the solid particles to be coated in an aqueous medium to produce a solid particle dispersion, adjusting the pH of the solid particle dispersion by a buffer system to produce a buffered solid particle dispersion, and adding an alkaline silicate solution to the buffered solid particle dispersion to form the silica coating on the solid particles during a coating period. The amounts of buffer system and alkaline silicate solution are selected such that the pH of the buffered solid particle dispersion before the addition of the alkaline silicate solution is at least 7.0 and after completion of the addition of the alkaline silicate solution is at most 11.0. |
