Abstract

The aim of the present work was to investigate rheological behaviour of alumina suspensions, considering different amounts of polyvinyl alcohol (PVAL) 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 an 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. Copyright © 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
