<p><P>PROBLEM TO BE SOLVED: To provide porous aluminum which can be effectively used for catalytic reaction and electrode reaction, includes a binder metal powder wall with a large surface area and also has excellent corrosion resistance. <P>SOLUTION: In the porous metal with a void P at the inside obtained in such a manner that, from the sintered compact of a press-molded body including metal powder and supporting powder having a melting point higher than that of the metal powder, the supporting powder is removed, the cross-section of a binder metal powder wall W forming the circumference of the void P has the area occupancy of the binder metal powder in 40 to <80%. Further, in the porous metal, the surface of the binder metal powder wall W of the porous metal is provided with an oxide film. There are also provided the methods for producing them. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
