Sažetak
The aim of this research was to prepare a stable and highly (65 wt.%) loaded aqueous alumina suspension and to investigate the influence of binder addition on the rheological properties of the prepared suspensions. For that purpose, alumina suspensions with dispersant concentration from 0.3 to 0.7 wt.% were prepared and their viscosities were analysed. Also, suspensions with optimal dispersant concentration and polyvinyl alcohol (PVA) based binder with different amount, from 1 to 4 wt.%, were prepared and their rheological behaviour was analysed. It was found that concentration of 0.4 wt.% dispersant is optimal for preparation of 65 wt.% alumina suspension. Also, addition of PVA binder into stable alumina suspension affect rheological properties, i.e. increases viscosity and shear stress.
