Electrophoretic deposition of Al2O3 and ZrO2 powders from isopropanol suspension in the presence of monochloroacetic acid under constant-current conditions was studied. The deposits were prepared under different electrical conditions of deposition. It was found that the deposits prepared at low current densities (500 mu A) contained smaller pores and achieved higher green densities than deposits prepared at high current densities (20 mA). The deposits prepared at low current densities were formed just by part of the particles in the suspension because of decreasing of efficiency of electrophoretic deposition process.
