Abstract: A new route for the production of freestanding porous structures based on the electrophoretic deposition (EPD) of particle-stabilized emulsions is described. Emulsions of paraffin oil in ethanol, stabilized with α-alumina particles were prepared using a magnetic stirrer. These emulsions were consolidated using EPD under a constant electric field into disk shaped specimens. The pore forming liquids are extracted prior to sintering by means of evaporation. The pores in the sintered disks are spherical and their size can be tuned within the 2 to 200 μm range. Both open and closed porosity can be obtained by varying the emulsion composition. Since no pore forming fugitive solid organic binder is used, the very delicate and time consuming debinding step during conventional processing is eliminated.
