| Abstrakt: | Abstract: The rheological character and the viscosities of aqueous alumina slurries with particle sizes between 0.62 and 1.9 mm are determined by rotational viscometer measurements. It is shown that the optimum electrolyte concentration in the slurries is clearly proportional to the specific surface of the powder contained and that the viscosity of the slurry (for this optimum electrolyte concentration) increases with increasing powder surface. Thus, apart from the solid phase and electrolyte content, the powder particle size is of principal importance for the rheological properties of the slurry. The maximum solid phase content for slip-casting and the long-term stability are determined for the respective slurries. |
