A system and method are disclosed for producing uniform size silica particles by the steps of providing preformed colloidal silica particles having a surface area, adding an alkali metal silicate and a cation exchange resin to produce a quantity of feed silica at a feed rate which is less than a nucleation rate, and increasing the feed rate as the feed silica is added wherein the feed rate is less than the nucleation rate. |
