Sažetak
The influence of a dispersant, polyelectrolyte DOLAPIX CE 64, on rheological properties of highly concentrated alumina-zirconia suspensions was investigated. Prepared suspensions contained 70 wt. % of dry ceramic powder. Two groups of composite alumina- zirconia suspensions were prepared, as well as one control suspension, containing only alumina. Ratio of alumina and zirconia was 99:1 for the first group and 90:10 for the second one. The amount of chosen dispersant was varied within the each group in order to determine the optimal one. Rheological properties of prepared suspensions were determined by measuring the apparent viscosity at different shear rates. The optimal amount of DOLAPIX CE 64 was the one resulting in the lowest apparent viscosity. It was established that the amount of added dispersant increases with the increase of zirconia content, but it can be confirmed that the chosen dispersant is applicable for this system.
