Abstract

The fabrication of planar zirconia green bodies with unidirectionally aligned pore channels by electrophoretic deposition with simultaneous electrolytic gas bubble formation using different platinum gauzes and, for comparison, platinum foil as deposition electrodes is described. The electrode has a strong influence on the pore structure. At suitable mesh sizes, a very regular arrangement of the tubular pores corresponding to the gauze structure can be obtained.
