Paper Abstract

Silica syntheses have performed by acidification of water glass under various reaction conditions and analyzed beams of SAXS method. SAXS spectra recorded during simultaneous dosing of water glass and sulfuric acid have shown clearly that primary SiO2 particles grow continuously and rapidly during the precipitation. In addition, the primary particles have a rather narrow size distribution, what is surprising result, since the particles are continuously involved in a number of processes: growing, forming interparticle bonds and aging.
