Abstract
In this study, porous ZrO2 ceramics were successfully prepared by an electrophoretic depositions (EPD) method with gas generation in the aqueous ZrO2 slurry. Especially, this aqueous EPD process in combination with a sintering step formed porous ZrO2 with a number of unidirectionally aligned continuous pores. Also, adding starch into ZrO2 slurry resulted in the increase of porosity of ZrO2 ceramics. Thus, applying the aqueous EPD process has a great advantage in environmental issues and cost reduction for fabricating porous ceramics.
