Abstract

Adsorption mechanism of dispersant PMAA-NH₄ on BaTiO₃ was studied by using ζ potential and FTIR spectrum. After the addition of PMAA-NH₄ the results show that the positive charge, Ba-OH⁺₂, existing on the surface of BaTiO₃ adsorbs the negative ion of the dispersant. The surface charge of BaTiO₃ changes and its IEP moves from pH=5.1 to pH=3.5. When pH=10, the concentration of PMAA-NH₄ is 0.8 wt%, the adsorption comes up to saturation and stabilized BaTiO₃ suspension can be obtained.
