Patent ID: 7560154

Claim:
A method for manufacturing a honeycomb structure comprising the steps of: machining a peripheral portion of a honeycomb substrate having a plurality of cells separated by porous partition walls made of ceramic, applying slurry for forming a coating member on a face exposed to outer periphery of partition walls positioned in the outermost periphery to obtain a honeycomb body with slurry, and subjecting the honeycomb body with slurry to heat-drying to obtain a honeycomb structure having the coat member in the outer periphery thereof; wherein the slurry for forming a coat member contains a powder of potsherd having a particle size of 15 to 75 μm, and the slurry has a water content of 26 to 34% by mass, wherein the heat-drying is performed by any one of hot-air drying, far-infrared ray drying, and a combination of far-infrared ray drying and hot-air drying.
