Method of fabricating inorganic filter structures

摘要

The invention consists in a method of making inorganic filter structures of the type consisting in: in shaping and baking a porous substrate; in depositing on the substrate a suspension containing at least one sinterable composition designed to constitute a filter layer after baking; in selecting, as the sinterable composition, a powder including at least aggregates made up of individual particles; and in destroying the aggregates contained in the sinterable composition in such a manner as to cause the composition to be composed essentially of individual particles.
