ELECTRODE, ELECTRICALLY HEATED CATALYTIC CONVERTER USING SAME AND PROCESS FOR PRODUCING ELECTRICALLY HEATED CATALYTIC CONVERTER

摘要

One embodiment of the present invention pertains to an electrode which is to be formed on a substrate consisting of a ceramic. The electrode is provided with: a matrix which consists of an Ni-Cr alloy (wherein the Cr content is 20 to 60 mass%) or an MCrAlY alloy (wherein M is Fe, Co, and/or Ni); and a dispersed phase which consists of an oxide mineral having a layer structure and which is dispersed in the matrix. In the cross section of the electrode, the area fraction of the dispersed phase is 40 to 80%. By virtue of such a configuration, the increase in the electric resistance of the electrode can be minimized even after the electrode has undergone heat cycles.
