Abstract

The relationships of dispersion-aggregation state of particle suspensions and w ettability，zeta potential of particles are examined．On the basis of experimental measurements and potential energy calculation，the mechanism of particle dispersion is discussed．

Keywords：hydrophilic particle hydrophobic particle；dispersion-aggregation state；mechanism of particle dispersion
