    摘要： A process for preparing a metallic porous body, comprising: forming a layer comprising Cu, a Cu alloy, or a precursor thereof onto a skeleton composed of a porous resin body having a three-dimensional network, heat-treating the resin body with the layer formed thereon to remove a heat-decomposable organic component, thereby forming a porous metallic skeleton of Cu or a Cu alloy; and plating the surface of the Cu or Cu alloy skeleton with Ni or an Ni alloy. The heat treating may be carried out by direct induction heating. The metallic porous body is useful as electrodes for batteries, various filters, carriers for catalysts, etc. When the porous body is cut and used as the electrode substrate, the coating of an area, where Cu or its alloy has been exposed by cutting or the like, with a third metal having a lower ionization tendency than Cu or its alloy can provide an electrode substrate having better corrosion resistance and battery service life.

    摘要： A porous metal body is produced by forming a coating film of one or more metal capable of forming a eutectic alloy at temperatures not higher than the melting point of Al on a foamed resin skeleton having a three-dimensional network structure according to the plating, vapor deposition, sputtering, CVD or other vapor phase process, impregnating the foamed resin having the coating film formed thereon with a paste comprising powdery Al, a binder and an organic solvent as principal components to thereby obtain a paste-coated composite and heating the composite at a temperature ranging from 550.degree. C. to 750.degree. C. in a nonoxidizing atmosphere. The resultant porous metal body has a large effective surface area and a high space utilization factor and exhibits excellent performance in uses in filters and battery plates.

    摘要： A battery electrode substrate which is constituted of a porous metallic body structure having communicating pores at a porosity of at least 90% and an Fe/Ni multilayer structure wherein the skeletal portion of the porous metallic body is composed mainly of Fe and has an Ni covering layer on the surface thereof while pores communicating with the inside and outside of Fe skeletal portion exist in the Fe skeletal portion and the inside of the pores is covered with Ni. The electrode substrate is produced by applying an iron oxide powder of at most 20 .mu.m in an average particle size on a porous resin core body; heat treating the core to remove an organic resin component while simultaneously sintering Fe to obtain a porous Fe body; and then covering the Fe skeletal portion with Ni by electroplating. In this process, the iron oxide can be used in combination with carbon powder. Further, a nickel porous sintered body can also be produced using nickel oxide in place of iron oxide.
