METHOD FOR PRODUCING CORDIERITE-BASED HONEYCOMB STRUCTURE

摘要

A method of manufacturing a cordierite-based honeycomb structure, comprising: adding an alumina source material, a silica source material and a magnesia source material to obtain a cordierite forming material; obtaining a clay by use of the resultant cordierite forming material; extruding the resultant clay into a honeycomb shape to obtain a formed honeycomb body; drying the resultant formed honeycomb body to obtain a dried honeycomb body; and firing the resultant dried honeycomb body to manufacture the cordierite-based honeycomb structure, wherein a first alumina source material having a degree of circularity of 0.70 or more and an average particle diameter of 1 to 10 µm is added as at least the alumina source material in an amount of 10 mass% or more with respect to the total mass of the cordierite forming material to obtain the cordierite forming material.
