Nano-silica is currently one of the most widely used nano-material，but its agglomeration behavior is disadvantageous to particle size measurement and application effect.In order to reduce the agglomeration behavior of silica nanoparticles，the dynamic light scattering particle size analysis method was applied to investigate the effect law of dispersion method，dispersant type and suspension conditions on the particle size and polydispersity index（PDI） of different silica nanoparticles.The experimental results showed that 0.1%（mass ratio） of PEG-2000 had a good dispersion effect on all kinds of nano-silica under stirring magnetic conditions.The particle size and PDI of silica sol suspensions showed a decreasing trend as the increased pH of suspension because the pH of suspension affected the dissolution equilibrium of silica sol，while the particle size and PDI of solid silica suspension showed a rising and then decreasing trend，which was due to the fact that the suspension pH affected the bilayer structure.In practical tests and applications，attention should be paid to the effect of suspension formulation conditions and the class of nano-silica on the particle size and PDI.
