Abstract
Discrete element modeling (DEM) was applied for simulating the powder packing dynamics during electrophoretic deposition of electrostatically stabilized ZrO2 (powder size 1 μm) and tape casting of BaTiO3 (powder size 0.3 μm) stabilized by polymer adsorption. The results indicate that a transition zone of ordering is supposed to exist ahead of the growth front of the solid sediment during electrophoretic deposition. Local variation of the shear rate in the tape casting process with increasing distance from the blade gives rise for the generation of particle clusters under low shear, and cluster disintegration (shear thinning) under high shear conditions. Thus, DEM simulation provides a detailed insight into local variations of particle interaction processes during consolidation which can be used for optimization of the shaping process of colloidal ceramic powder suspensions.
