The polycondensation of silicate to form colloidal silica is a well-known process. Silica formation takes place through an S_N2-like mechanism that involves an attack of a mono-deprotonated silicic acid molecule on a fully protonated one. Thus, monomeric silicate species produce silicate dimers, and oligomers, and eventually form colloidal silica particles. Nevertheless, this straightforward silica chemistry can be profoundly affected by the presence of certain metal cations, such as calcium, magnesium, aluminum, and iron. When such cations are present in a process water they enhance the rate of polymerization of silicate ions and induce the formation of metal silicate precipitates.
