Sažetak
Stability of highly concentrated (70 wt. %) aqueous suspensions of monolithic and composite ceramics suitable for slip casting was monitored by rheological properties measurements (flow curves and rheological parameters). Three groups of suspensions were prepared: monolithic Al2O3 and composite Al2O3– t-ZrO2 ceramics (composition: 95 wt. % Al2O3 – 5 wt. % t-ZrO2 and 90 wt. % Al2O3 – 10 wt. % t- ZrO2) with different amount of dispersant DOLAPIX CE 64. Recorded flow curves were fitted to the power law, Herschel-Bulkley and Bingham models. Minimal viscosity was determined for each prepared suspension, in order to determine optimal slip casting parameters. Obtained results showed that the amount of dispersant for required minimal viscosity increases with the increase of the t-ZrO2 amount.
