Ceramics International, 2002•ElsevierThe viscosity and shear rate as a function of 2–24% volume concentration of solids was
determined for alumina and kaolin slurries. A model of viscosity as a function of volume
concentration of a dispersed phase in a matrix and a bidimensional balance of forces acting
on a particle in suspension is presented. The theoretical model was compared with
experimental data accomplished with a double concentric cylinders rheometer. A good
correlation of the proposed model with the measured data could be verified. The forces of …

The forces of mechanical origin that cause restrictions to particle rotation and translation appear to remarkably influence the variation of viscosity.
