The deposits of nano-sized gamma-Al2O3 powders were fabricated via a simple electrophoretic deposition process in aqueous suspensions. Bubble-free deposits of nano-gamma-Al2O3 powders with a uniform microstructure and high green density up to 56.8% were successfully obtained. Some factors that contribute to the deposition characteristics of the EPD in an aqueous suspension are discussed. (C) 2002 Elsevier Science Ltd. All rights reserved
