Abstract

Abstract: Asol gel mechanism is proposed in this research for the process of silicon dioxide film coating on Titanium dioxide particles. The dynamic process of film forming on the particle surface is researched. The influence of temperature and concentration on film formation rate is researched. The dynamic equation of the film formation of silicon dioxide is obtained from the experiments. The theoretically calculation results are consistent with the experimental results.
