CERAMIC FILTER FOR SUPPORTING A CATALYST, AND MANUFACTURING METHOD THEREFOR

WIPO Patent Application WO/2010/146954

A1

Disclosed is a ceramic filter for supporting a catalyst, whereby a low thermal expansion coefficient can be obtained without requiring precoating before inorganic particulate film formation. Also disclosed is a method for manufacturing said ceramic filter. The disclosed ceramic filter for supporting a catalyst on the filter surface is characterized by the provision of: a ceramic filter body formed from an aluminum titanate having a mean aspect ratio (the number average long-axis length divided by the number average short-axis length) of at least 1.3; and an inorganic particulate film provided directly on the surface of the ceramic filter body in order to increase the specific surface area thereof.
