The Mechanism of Low pH Silica Based Oxide Slurries

Much lower removal rates are obtained with colloidal silica at similar concentrations For instance fumed silica yields a removal rate of 2700 /min on TEOS while colloidal silica has a removal rate of 410 /min at pH 12 At a pH less than 7 the removal rate for colloidal silica is a mere 90 /min
