“…, fructose does not lead to any shift in the isoelectric point of the nano alumina particles. A similar observation was reported by Falkowski et al . It is also worth noting that the change in pH is another proof of the interaction of the fructose with the alumina surface.…”

Control of the rheological properties of the nanoparticle suspensions is challenging. In this study influence of the solids content and the fructose addition on the viscosity of nano alumina suspensions have been investigated by low temperature differential scanning calorimetry (LT‐DSC), rheometry, and zeta potential measurements. Analysis of the water melting events in LT‐DSC revealed useful information for explaining the rheological behavior of the nanoparticle suspensions. It was shown that the bound water layer has a negligible effect on the viscosity of micrometer‐size particle suspension while it increases the effective solid content of alumina nanoparticle suspensions significantly leading to high viscosities. The presence of fructose modifies the bound water layer, decreases the effective solids content, hence resulting in viscosity reduction. Fructose addition lowers the pH of the suspension, but has a negligible effect on the zeta potential. The origin of the bound water, and electrostatic and steric effects of the fructose addition on the viscosity are discussed.

“…For this reason the rheological measurements of intensifies the action of the dispersant. This observation is in a good agreement with the research showing that saccharides and their derivatives may be used as dispersing agents for nano-and submicron-sized oxide powders [29,30]. A little different behaviour is observed when HEA is used.…”
