| Abstract: In this study,using hydrochloric acid solution in different concentration as acidifying agent,the change in sub-micromechanism during gelation process of solution of sodium monosilicate has been investigated by micro-videotape and a scanning electron microscope. By summarizing up all the experimental results it is found that in alkaline solution the gelation process of silicic acid is dividied into three steps: formation of the polysilicic acid molecular chain,molecular chain beam and the network skeleton of silicic acid gel. |
