dc.description.abstract | Colloidal dispersion of two submicron alumina powders (A-16SG and APA-0.2) and their mixtures were investigated in an aqueous suspension with and without dispersant (ammonium salt of poly(methacrylic acid), PMAAN). The ζ-potential and isoelectric point (iep) of the powders in aqueous solution were determined in the presence of the dispersant and electrolyte (NaCl). The adsorption of dissociated PMAA- on alumina powders was determined via the titration technique. The dispersant was observed to exert a strong influence on the surface potential, flowing behaviors and packing densities of the aluminas. The results showed that the dispersion conditions were strongly affected by factors including the solid concentration of submicron alumina particles, the pH value and the concentration of PMAAN in the suspensions, and that these three factors were cross-influencing. A reaction model at the interface of alumina-solution was developed, based on the dissociation of PMAAN and the adsorption of surface hydrocarboxyl groups on alumina surface. © 1995. | - |
