The influence of pH and temperature on the rheology and stability of aqueous titanium dioxide dispersions

Correlation between the Zeta Potential and Rheological Properties of Anatase Dispersions

“…A rather insignificant temperature effect on the viscosity of rutile dispersions is reported in Ref. (16). The temperature effect on the viscosity of titania dispersions may be partially due to the temperature effect on the PZC (14).…”

The rheological behavior and stability of Mg(OH)2 aqueous suspensions in the presence of sodium polyacrylate

“…Therefore, more disperse phase liquid is immobilized in the void spaces within flocs and this results in a relatively high viscosity [32,33]. As the shear rate increases, the flocs are gradually destroyed and the entrapped liquid is released, hence leading to the shear thinning behavior [34,35].…”

Rheological Behavior of Titanium Dioxide Suspensions

“…Effect of particle concentration on shear viscosity for broad size distribution powder: +, φ = 0.431; ᭜, φ = 0.378; ᭢, φ = 0.282; ᭡, φ = 0.238; ᭹, φ = 0.185; , φ = 0.174; ×, φ = 0.109; the solid lines are fits to Eq. [4] or [7].…”

“…[13] Equations [12] and [13] respectively are used in conjunction with Eq. [7] to correlate the viscosity data obtained in the temperature range 20-40…”

“…Measurement of the pH after rutile addition indicated H + or OH − adsorption to achieve the final pH (6). The effects of pH and temperature on the rheology and stability of aqueous dispersions of rutile were investigated in the past by the groups of Mikulasek and Liddell (7,8). Though many theoretical and experimental works have focused on the relationships between rheological properties of titanium dioxide suspensions and factors affecting them, few of them showed a conclusive relationship due to the complexity of the suspensions.…”
