Dispersion Behavior of Nano-powder TiO2 and SiO2-Ag in Aqueous Solution
The effects of dispersant on dispersion of nano TiO2 and SiO2-Ag particles were investigated respectively. The sedimentation height and the size distribution of the dispersed particles in aqueous solution were employed to characterize the particles dispersion. The experimental results show that (NaPO3)6 is efficient dispersant for TiO2 and SiO2-Ag particles in aqueous solution. The zeta potential of the particles in aqueous solution was measured to analyze the dispersion mechanism since (NaPO3)6 can significantly increase the absolute value of zeta potential of particles. Thus satisfactory and stable dispersion of TiO2 and SiO2-Ag in aqueous solution is obtained.
