Dispersion of TiO_2 Nano sized Particles in Liquor

Feng La

Abstract

Dispersion process of the TiO2 nano sized particles in water is studied.The effects of mechenical agitation,inorganic electrolytes and surfactants of dispersion of TiO2 nano sized particles are discussed. The result indicates that a good dispersion stabilization of TiO2/H2O suspension system can be obtained by machanical agitation and adding inorganic electrolytes (Na4P2O7·10H2O,(NaPO4)6),surfactants (sorbitol,Triethanolamine,OP-10,SDBS)and adjusting pH value in water as the dispersion medium.
