Document Type and Number:
WIPO Patent Application WO/2018/043603
Kind Code:
A1
Abstract:
Provided is a method for producing an aluminum porous body having a large surface area. The method for producing an aluminum porous body according to the present invention comprises: a step for producing, as a precursor, an aluminum alloy cast body having a solidified structure having an α-Al phase 1, and a second phase formed continuously and intricately with the α-Al phase, by casting solidification of an aluminum alloy; a step for producing an aluminum porous body having a large number of voids 2 the insides of which are connected with the surface, by bringing the precursor into contact with an eluent for dissolving the second phase, and thereby eluting the second phase of the solidified structure in the precursor; and a step for conducting a thermal treatment after the step for producing the precursor.
