Abstract

The coating of conductive polypyrrole (Ppy) on nonconductive ceramic substrates was carried out. Thick, crack-free deposits of alumina powder were formed on the Ppy coated ceramic substrates by electrophoretic deposition (EPD). Adhesion of the deposits to the Ppy surfaces was fairly good. Alumina ceramics with complex shapes were successfully obtained by sintering the deposits together with the substrates in air.
