Abstract Scope |
Alumina is an exemplary model system to investigate how the rheology of colloidal suspensions can be exploited to achieve uniform dense ceramics. Alumina powders were obtained by milling then slip cast as both dispersed and coagulated suspensions. Two-step sintering was used to obtain fine-grained, dense microstructures and the densification compared to the initial particle size and the concentration of agglomerates. The results showed, perhaps surprisingly, that coagulated suspensions exhibited better densification compared to dispersed suspensions. |
