摘      要：Silicon dioxide sol was synthesized by silicon in the presence of alkali catalyst. SiO_2 nanoparticles (size in 8-15 nm) aqueous dispersion was prepared by using dispersion and surface modification in situ. The effects of reaction time, temperature, medium pH value, dispersant and surface-modifier on their diameters, sizes distribution and dispersion stability were also *** experimental results show that the preparation method can effectively resolve the dispersion stability of SiO_2 nanoparticles in water.
