1. Introduction. Precipitated silica (PS) has been widely used as effective filler for plastic, rubber, and paint,,,, .In particular, it has been considered as a green filler in the tire industry where it is assumed to contribute to the reduction of energy consumption and the emission of CO 2.Precipitation of silica from sodium silicate and sulfuric acid is an economic way to synthesize PS.
