摘要

Process for the preparation of silicic acids and precipitated silicates modified with organic compounds, by impregnation of the silicas or silicates with waxes or synthetic materials, characterized in that during and/or after the precipitation of the silicic acids or silica gels or silicates from solutions of alkali metal silicates with acids or metal salts, an aqueous emulsion or dispersion of a wax or water-insoluble synthetic material, inert, colorless and high-point, is added to the suspension or aqueous dispersion of the silicic acid or silicate. Melt, and the filler is subsequently filtered, the filter cake is washed, dried and finely ground. (Machine-translation by Google Translate, not legally binding)
