Experimental study on zeta potential and streaming potential of advanced ceramic powders

An improved method for determining zeta potential and pore conductivity of porous materials

“…Generally, the zeta potential of ceramic for pure water is in the range between 10 and 30 mV. Our data agree reasonably well with published data [3,16]. If we neglected the resistance between channel end and electrodes, the zeta potential would be underestimated, as shown in Table 3 from the classical method.…”

Solvent effect on synthesis of indium tin oxide nano-powders by a solvothermal process

“…7 illustrates the solvent effect on the electrokinetic behavior of ITO as a function of suspension pH at a particle weight fraction of 1%, where suspensions were prepared with ITO powders crystallized in various organic solvents and water as solvent. 27 This verifies that the degree of reduction varies depending on diverse types of solvent in the solvothermal process. The isoelectric points of all suspensions exhibited nearly in a neutral region between pH 7 and 8.…”

Controlling Coagulation Process: From Zeta Potential to Streaming Potential

“…For the suspensions with 10% solids loading, correlation coefficients are slightly lower due to the influence of increasing viscosity. Regardless of lower correlation at the higher solids loading, the isoelectric pH is constant within the limits of accuracy of the pH measurements [19].…”

“…In their study, Wäsche et al [19] compared Zeta potential, as evaluated with the electrokinetic sonic amplitude method, to streaming potential as evaluated with the particle charge detection method. The measurements have been realized on identical suspensions of α-Al 2 O 3 , SiC and Si 3 N 4 with a solids volume fraction of 1% and 10%.…”
