Studies were performed on the precipitation of silica from aqueous solution of potassium metasilicate and sulphuric acid. The surface modification of precipitated silicas using silane coupling agents was undertaken. The obtained silicas were subjected to physicochemical appraisal. The surface charge of the obtained dispersion, particle size and shape of the formed silicas were estimated.
