| Abstract | |
The flow properties of high solids concentration suspensions has been extensively studied and established, however, the rheological behavior for ceramics suspensions with very high solids loading, up to 60 vol.% is poorly known. This is due to both difficulties of preparation and behavior measurement. The theory shows ceramics suspensions with very high solids loading may present viscoelastic properties attributed to interparticle forces active. The oscillatory and creep-recovery rheological measurements can provide this knowledge when discretion used. Thus, rheological behavior of alumina suspensions with high solids loading (>43 vol.%), properly stabilized and the characterization of slip casting shaped samples has been analyzed. High solids loading suspensions, over 43 vol.%, present adequate flow and suspensions with solid content since 60 vol.% present viscoelastic properties attributed to interparticle forces active. The rheological parameters can provide subsidies to obtain after shaping process, such as extrusion, injection and plastic pressing, suitable products for the desired application.
