CERAMIC HONEYCOMB STRUCTURE, CERAMIC HONEYCOMB CATALYST CARRIER, AND CERAMIC HONEYCOMB CATALYTIC CONVERTER USING THE SAME

摘要

A material having a thermal expansion co-efficientapproximately the same as that of a catalyst is adhered tothe entire outer side of an outer wall of a ceramichoneycomb structure or a ceramic honeycomb catalyst carrier,thereby providing a ceramic honeycomb structure, ceramichoneycomb catalyst carrier, and ceramic honeycomb catalyticconverter using these. These structure, catalyst carrier,and catalytic converter are capable of preventing cracks atthe perimeter of the ceramic honeycomb catalyst carrier, andhence capable of preventing damage to the ceramic honeycombcatalyst carrier in a sure manner.
