Abstract
Dispersion behavior of hydrophilic calcium carbonate particles and hydropho bic talcum particles in water, ethanol and kerosene media has been studied by sedimentation analysis. It is found that the dispersion of fine particle s complies with the principle of polarity compatibility. That is to say, th e dispersion effect will be improved when surface polarity of particles is similar to that of liquid media. The adsorption models of oleic acid on the surface of particles in water and ethanol are proposed.
