%X Adsorption mechanism of dispersant PMAA-NH4 on BaTiO3 was studied by using potential and FTIR spectrum. The results show that the positive charge, Ba-OH2+, existing on the surface of BaTiO3 adsorbs the negative ion of the dispersant. The surface charge of BaTiO3 and its IEP from pH=5.1 to pH=3.5 change after the addition of PMAA-NH4. When pH=10, the concentration of PMAA-NH4 is 0.8wt%, the adsorption comes up to saturation and stabilized BaTiO3 suspension can be obtained.
