POROUS ALUMINUM AND PROCESS FOR PRODUCING SAME

摘要

Provided is a method for readily removing urethane resin without causing oxidation of aluminum, from an aluminum structure in which an aluminum film is formed on the surface of a urethane resin porous body having a three-dimensional network structure: a method for producing an aluminum porous body, including forming an aluminum film having a purity of 99.9% by mass or more on a surface of a urethane resin porous body having a three-dimensional network structure to provide an aluminum structure including the urethane resin porous body and the aluminum film, and subjecting the aluminum structure to a heat treatment at 370° C. or more and less than 660° C. in the air to remove urethane resin and to provide an aluminum porous body.
