A continuous process for producing a precipitated silica slurry is described. In the process, an aqueous metal silicate compound, an acid and an electrolyte are continuously fed to a mixing zone produce a reaction mixture. The reaction mixture is maintained at a temperature of less than about 100 DEG C in a quiescent zone. The reaction mixture is continuously removed from the quiescent zone. The precipitated silica slurry produced in accordance with the present process has a relatively narrow particle size distribution and may be dispersed more easily than currently available silica materials. |
