Abstract
The dispersion and rheological behavior of alumina, zirconia, and alumina/zirconia mixed slurries were investigated using various solvent ratios of methyl isobutyl ketone (MIBK)/ethanol (EtOH), by measuring sedimentation bulk density, particle size distribution, and viscosity. Well-dispersed suspensions were obtained in MIBK-rich solvents with additional dispersant and in EtOH-rich without dispersant. The shear viscosity of the slurries was dependent on both the Al2O3/ZrO2 ratio and MIBK/EtOH ratio. At a constant solvent ratio, however, similar rheological behavior was shown regardless of the relative amounts of the two solids. At low shear rate, a Newtonian plateau was absent in the Al2O3/ZrO2 slurries. With increasing shear rate (>600 s(-1)), Al2O3 slurries exhibited a Newtonian plateau while ZrO2 demonstrated continuous shear thinning.
