Surface forces in suspensions must be controlled if optimum processing is to be achieved as they govern their processing behaviour. Surface chemistry tools such as pH, ionic strength and adsorbed additives are often used to effect and control these f

The yield stress-pH and zeta potential-pH behaviour of α-alumina and zirconia dispersions with adsorbed small ionic molecular additives such as phosphate and pyrophosphate were determined. The result for adsorbed citrate was included for comparison.

The linear relationship between yield stress and the square of the zeta potential based on the yield stress–DLVO force model, was used to determine the zeta potential at the point of transition from flocculated to dispersed state of a range of oxid

The yield stress and zeta potential (ζ) of slurries prepared from as-received goethite were evaluated as a function of pH, solids concentration, cationic polyethylenimine (PEI) concentration and molecular weight (Mw). The goethite slurries displayed

The yield stress-DLVO force relationship is obeyed by α-Al 2 O 3 and alumina-coated TiO 2 dispersions with adsorbed polyacrylate only if the yield stress and its corresponding zeta potential data were collected in the positively charged region. In t

This paper aims to show a novel yield stress-zeta potential technique for determining the critical zeta potential of α-Al2O3 and ZrO2 dispersions at the flocculated-dispersed state transition and a mean for determining the Hamaker constant of oxides

The critical zeta potential characterises the flocculated–dispersed state transition of a colloidal dispersion. For many colloidal dispersions, yield stress displayed a linear relationship with the square of zeta potential indicating that they obey
