Abstract
A process, particularly a continuous process, for industrially producing a high-quality inexpensive porous iron metal while preventing the conventional rusting problem which process comprises coating the surface of a conductive porous base material by iron electroplating, removing the base material, and then reducing the coating. The iron electroplating was conducted in an acid iron plating bath which contains at least one from acid aluminum compound and/or at least one acid titanium compound, using an anode which contains at least either of aluminum and titanium and has a surface area not smaller than 1/3 of and not larger than that of the base material. The reduction is conducted by a two-step heat treatment for improving the iron structure and for softening.
