ABSTRACT:
A porous metal body having a foam structure of 500 μm or less in average pore diameter, wherein the skeleton is composed of an alloy primarily including Fe and Cr, and Cr carbide or FeCr carbide is uniformly dispersed in the texture. The metal porous body is produced by preparing a slurry primarily containing an Fe oxide powder having an average particle diameter of 5 μm or less, at least one powder selected from metallic Cr, Cr alloys, and Cr oxides, a thermosetting resin, and a diluent, applying a coating of this slurry to a resin core body having a foam structure, performing drying, and thereafter, performing firing in a non-oxidizing atmosphere so as to produce a metal porous body having the aforementioned skeleton structure.
