Kinetics of heterocoagulation. 3. Analysis of effects causing the discrepancy between the theory and experiment

Dynamic Features of Short-Range Interaction Force and Adhesion in Solutions

“…There are the other reports claiming that the repulsive force between silica surfaces is explained by the hydration of surfaces rather than by a gel layer (8,9). The existence of a thick structured layer is also suggested by coagulation experiments with silica dispersions (24) and rheological studies on silica and aluminum slurries (25)(26)(27).…”

Stability in Colloidal Mixtures Containing Particles with a Large Disparity in Size

“…[2]), is limited to systems for which both sets of primary particles have either identical or very close values of the scattering intensities associated with single (individual) particles at the angle of observation (6). For such systems, experiments are usually carried out for binary mixtures at a constant value of the total particle number concentration (N tot ), but varying the ratio (N 1 /N 2 ) of the two individual particle number concentrations.…”

The Stability Behavior of Sol-Emulsion Systems

“…As noted earlier, show the low-pH region to be one of significant heteroagthe general analysis of McCormack et al (6) is used for the gregation, while at pH values above approximately 7 (near computation of the pair interaction potentials, and W 12 values the isoelectric point for the TiO 2 ), no significant heteroagare computed as in Eq. [3]. Measured zeta potentials are gregation is expected.…”
