N2 - Many advanced ceramics are formed by colloidal consolidation using techniques such as sedimentation, centrifugation, or pressure filtration. The goal of this paper is to examine the equilibrium-state density profiles of centrifuged cakes of flocculated suspensions both theoretically and experimentally. The emphasis is to take into account the effect of the consolidation pressure by relating the equilibrium-state density profiles to the pressure-cake-density relationship. By equilibrium state, the authors mean the stage in which the cake height no longer changes with time. Theoretically, the equilibrium-state density profiles of centrifuged cakes were obtained by implementing the experimentally obtained pressure-density relationships into the general differential equations and solving the differential equations with appropriate boundary conditions. Experimentally, the density profiles were examined by γ-ray densitometry.
