| description | The present invention relates to colloidal silicas having a low S-value and a high solids content, the preparation thereof, and the use thereof in the production of paper. When used in the production of paper, the colloidal silicas of the invention exhibit good retention and drainage performance so that they can be used in lower amounts compared to conventional colloidal silicas. The present invention also relates to an apparatus and a method for producing such activated colloidal silicas. |
