heal.abstract	Recently, a novel automotive catalyst design, based on the use of palladium supported on yttria-stabilized zirconia (YSZ), was proposed. In the present work, the coating of cordierite honeycomb samples with YSZ slurries for the preparation of such washcoats was investigated. The loading percentage, homogeneity, and reproducibility were found to depend strongly on the slurry viscosity. Parameters such as the slurry-solids content, pH, type of powder used, and use and quantity of the dispersants were optimized for the preparation of stable, low-viscosity YSZ slurries, adjustments that could lead to an efficient coating process for honeycomb structures.	en
