Summary

The electrophoretic mobilities of ceramic oxides are commonly examined in electrolyte solutions. In order to estimate the relationship between these data and conditions of stability in the actual processing environment, most commonly water, the electrophoretic mobilities of dilute aqueous suspensions of submicron Al2O3 and ZrO2 particles and their mixtures (containing 5-30 vol% ZrO2) were compared to the electrokinetic behavior of the same powders in 0.01 M KNO3 It was found that the points of zero charge (pzc) of the examined oxides in these specific media displayed substantial differences. Additionally, increasing the ZrO2 contents of the mixtures with Al2O3 introduced further changes to the ζ-potential values.
