METHOD FOR PRODUCING CORDIERITE-BASED HONEYCOMB STRUCTURE

摘要

A method for producing a cordierite-based honeycomb structure, which comprises preparing a raw material for forming cordierite from an alumina source material, a silica source material and a magnesia source material, preparing a body by the use of the resultant material for cordierite, extruding the resultant body into a honeycomb shape to prepare a honeycomb formed article, drying the resultant honeycomb formed article to prepare a dry honeycomb formed article, firing the resultant dry honeycomb formed article to prepare a cordierite-based honeycomb structure, wherein the above raw material for forming cordierite comprises a first alumina source material having a degree of circularity of 0.70 or higher and an average particle diameter of 1 to 10 µm in an amount of 10 mass % or more relative to the total mass of the raw material for forming cordierite.
