Abstract:
A filter element for a particle filter having a porous filter body made of a ceramic material and including a plurality of flow channels extending fluidically in parallel. The filter body is provided at least in a part of the flow channels with a coating made of a coating material, which is different from the ceramic material and is made up of orthorhombic crystals. A particle filter, a method for producing a filter element, and the use of a coating material for coating a filter element is also provided.
