| Abstract: | The colloidal stability of aqueous barium titanate (BaTiO3) suspensions with the ammonium salt of poly(methacrylic acid) (PMAA-NH4), as a function of pH, has been investigated. The concentration of PMAA-NH4 required to stabilize aqueous BaTiO3 suspensions decreases as the pH increases. A stability map that delineates the critical amount of PMAA-NH4 necessary to achieve colloidal stability, as a function of pH, has been constructed. |
