Cordierite ceramic filter and method of producing the same.

摘要

A cordierite ceramic filter is formed by mixing cordierite powders having a porosity of more than 30% as aggregate with raw materials for cordierite generation, poring agents, forming agents and solvents to obtain a ceramic batch, extruding the ceramic batch into a honeycomb shape to obtain a formed body, and firing the formed body. The cordierite ceramic filter has a mean pore size in a range of aggregate mean size x 0.15 +/- 5 mu m, has a porosity of more than 30% and has a compressive strength more than 100 kgf/cm<2> in a direction parallel to a flow passage. The cordierite ceramic filter has an excellent filter regeneration function, has a high mechanical strength and is light and compact.
