| Abstract: | In the present paper, the effect of electrolytic concentration on the gelling rate of silica sols has been studied by the method of gelation curve and viscosimetry. Tt is found that the logarithm of gelling rate of silica sols has a linear relationship with electrolytic concentration at a constant pH, the ratio increasing with the increase of pH (> 1.6). These phenomena are in agreement with the effect of electrolytic concentration on the stability of colloid solutions as descrfbed by the DLVO theory. |
