An 8 mol% yttria-stabilized zirconia (8YSZ) films are electrophoretically deposited on the La0.8Sr0.2MnO3 substrate using 8YSZ nanocrystallites prepared by a sol-gel process. Effects of liquid suspension on the particle zeta potential and degree of agglomeration at different pH values are investigated. When the pH value deviates from the point of zero charge (PZC), the adsorption of protons on particle surfaces cause higher zeta potential and well-dispersed suspension. The optimal values of the iodine concentration, applied voltage and deposition time for the electrophoretic deposition of 8YSZ films are also found. (c) 2006 Elsevier B.V. All rights reserved.
