Title:

ELECTRODE MATERIAL

Document Type and Number:

WIPO Patent Application WO/2015/133262

Kind Code:

A1

Abstract:

This electrode material results from reducing the size of and uniformly dispersing particles containing Cr, and also minutely and uniformly dispersing a Cu portion, which is a highly conductive component. The electrode material is prepared, for example, by means of: a mixing step (S1) for mixing a Cr powder and a heat resistant element powder; a provisional sintering step (S2) for obtaining a solid solution of Cr and the heat resistant element by means of provisionally sintering the mixed powder; a pulverizing step (S3) for obtaining a solid solution powder of Cr and the heat resistant element by pulverizing the solid solution of Cr and the heat resistant element; a molding step (S4) for molding the solid solution powder; a main sintering step (S5) for obtaining a sintered body (skeleton) of Cr and the heat resistant element by performing main sintering of the obtained molded body; and a Cu infiltration step (S6) for infiltrating the sintered body of Cr and the heat resistant element with Cu.
