Document Type and Number:
Japanese Patent JP5295196
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a metallic honeycomb base material for an exhaust gas cleaning catalytic converter having excellent oxidation resistance at high temperature, the durability of which can be improved at higher temperature even when a rare earth component, an alkaline-earth metal component, a group 4A metal component or a group 5A metal component is added to a catalyst layer and to provide the catalytic converter for cleaning exhaust gas.SOLUTION: There is provided a metallic honeycomb base material formed by fabricating a stainless steel foil, wherein a film of a precursor being structured with an oxide film is formed on the surface of the stainless steel foil, and the oxide film contains α-alumina and one or more kinds of spinel. The resultant base material exhibits excellent resistance to a high temperature and high oxidative atmosphere, and a catalyst converter for the clarification of an effluent gas using the material is provided.
