Sažetak
The aim of the present work was to investigate rheological behaviour of alumina suspensions, considering different amounts of polyvinyl alcohol as a binder. Three different aqueous suspensions were prepared, containing 60, 70 and 80 wt. % of alumina powder. Spinel was added as a sintering agent and Darvan 821-A as a dispersant, in the amount of 0.08 and 0.4 wt. % of dry powder weight, respectively. The alumina suspensions flow curves were recorded and fitted satisfactorily to the Power law, Herschel-Bulkley and Bingham models. Obtained results indicate that apparent viscosity of alumina suspensions increases with increasing Al2O3 and polyvinyl alcohol amount.
