POROUS METAL BODY, PROCESS FOR PRODUCING THE SAME AND BATTERY PLATE FORMED THEREFROM

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 pastecoated 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.
