Aqueous Silica And Silica Polymerisation | IntechOpen

Aqueous Silica and Silica Polymerisation | IntechOpen

colloidal silica is the result of the silico-oxygen acid polymerisation process . colloidal silica can form in bulk solution or ro feed when dissolved silica solubility exceeds the silica solubility limit. in csg waters, silica exists as either colloids or as un-dissociated (ortho-) silicic acid (h 4 sio 4) when the ph is between 8.5 and 9.2.
