Method for applying a washcoat dispersion (3) to a honeycomb body (1) having channels (2), the washcoat dispersion (3) preferably being a carrier material (13) evenly distributed in a carrier fluid with a mixture of stabilized, high-surface area aluminum oxide of the transition row and at least one promoter oxide, in which the honeycomb body (1) is brought into contact with the washcoat dispersion (3), the washcoat dispersion (3) being excited to vibrate at least during application. This prevents premature gelation of the washcoat dispersion and ensures a uniform washcoat thickness in the channels. |
