Abstract
An exhaust treatment apparatus for treating exhaust gas flowing through an exhaust line housing from an upstream location to a downstream location in a downstream direction, the exhaust treatment apparatus comprising a ceramic filter body having a honeycomb structure of a plurality of intersecting porous ceramic walls extending from a first end to a second end in an axial direction and defining a plurality of channels extending in the axial direction, wherein a first transverse face at the first end comprises metal oxide particles affixed to a portion of the intersecting walls. The metal oxide particles may be affixed to the upstream end, or the downstream end, or both the upstream and downstream ends. Preferably the metal oxide particles provide reinforcement to the underlying portion of the walls, and of the honeycomb structure itself.
