Dispersion properties of alumina powder in toluene solution of glyceril triolein (GTO) was studied. The amount of adsorption of GTO on Al2 O3, Zeta-potential and the electrophoretic current were measured and the properties of GTO as the dispersant were discussed. The effect of GTO addition on the dispersion of Al2 O3 was obvious at the GTO concentration of more than 0.5wt ％. The function of GTO as the dispersant was thought to be due to both steric and electrostatic effects but the electrostatic effect was not predominant.
