摘要

The rheological behavior of aqueous Al₂O₃/SiC suspensions at different pH values was investigated by rheological measurement. Experimental results showed that at pH = 3–6, Al₂O₃ and SiC particles have opposite surface charges, and the binary suspensions have lower viscosity than the unary suspensions at shear rates of 0–300 s⁻¹. Furthermore, at pH = 3–12, the stability of the Al₂O₃ component seemed to dominate the overall rheological behavior of the Al₂O₃/SiC binary suspensions. The tendency mentioned above showed little variations in various ionic strengths, particle diameters and component fractions.
