Interactions between Al2O3 and ZrO2 powder in a concentrated suspension

Abstract The electrophoretic mobility of Al 2 O 3 and two types of ZrO 2 powder was measured and correlated with viscosity measurements. Slip casting was performed at several total powder concentrations on the slips dispersed at pH 3 where the electrophoretic mobility of both Al 2 O 3 and ZrO 2 was high. ZrO 2 stratified in slips containing less than 20 vol.% solids but did not at higher concentration.
