Abstract
The influence of K+and Na+concentrations on the stability and rheological property of silica sol system have been studied by rheological method.The results show that the influences of K+ on the stability of silica sol is much larger than that of Na+.Under the low shearing rate,all discussing systems showed the typical disperse system of rheological properties,which is shear thinning.While under the high shearing rate,the resemble Newtonian fluid characteristics has been found.
