Slip casting behavior of a cylindrical body was analyzed by FEM(finite element method). Based on the assumption that the cake is uniform and incompressible, Laplace equation for liquid pressure can be derived. Cake growth per unit time was calculated by a sequential combination of the Laplace equation, Darcy's law and mass balances. The profile of solid front(the interface between cake and slurry)changed with time from a cylindrical curve to a parabolic one. This three dimensional profile can be attributed to the interaction of filtration to the bottom and side-wall directions in the cylindrical mold. In the early stage of slip casting, the results of numerical analysis were in reasonable coincidence with the profiles experimentally obtained. It was shown that FEM simulation is valuable for prediction of three-dimensional cake growth which can not be expressed by one-dimensional analytical approaches.
