Effects of powder characteristics on rheological properties of alumina slurries were preliminarily investigated by measuring the particle size distribution and flow curves under steady and oscillatory shear conditions. The particle size distribution of three kinds of alumina fine powders was fitted based on Rosin-Rammler distribution. The fractal dimension of the particle size distribution for alumina powders was related to powder characteristics. The increasing of the average particle size of alumina from 2.73 to 4.96 µm led to higher yield stress of slurries ranging from 0.015 up to 0.063 Pa. The rheological properties of alumina slurries varied not only with the particle size and its distribution but also with other factors such as morphology and surface status. |
