(JP10001797-A)      Porous Fe metal body is manufactured by: (i) electroplating an Fe coating onto a conductive porous base; (ii) removing the base by roasting; and (iii) reducing the coating.    The Fe plating bath is an acid plating bath containing an acid Al or Ti compound and the anode used contains Al or Ti and has a surface area of 1/3 and not larger than that of the porous base. The reduction comprises a two-step heat treatment consisting of improving the Fe structure and subsequent softening.    USE -   Used in batteries, filters, catalysts etc.    ADVANTAGE -   A high quality, low-cost porous Fe body is provided having low rusting tendency.    (US5725750-A)      Producing a porous iron metallic body comprises: (a) coating the surface of a conductive porous base material by iron electroplating, using an acidic iron-plating bath containing at least one of acid aluminium (Al) compounds and acid titanium (Ti) compounds, and using an anode containing elemental Al and/or Ti and having a surface area in the range 0.33 to 1.0 times that of the base material to be coated; (b) removing the base material by roasting; and (c) performing a reduction reaction on the coating, comprising a two-step heat-treatment in which the iron structure is improved by increasing crystallisation in the first step and is softened in the first step and is softened in a second step.    USE -   Used in producing a porous iron metallic body suitable for use in batteries, filters, catalysts, etc..    ADVANTAGE -   The process provides a continuous process for the industrial production of an inexpensive, high-quality porous iron metallic body. The product exhibits reduced rusting and is more resistant to corrosion.
