| description | PROBLEM TO BE SOLVED: To provide a metal porous body having a small pore diameter and having continuous pores, and to provide a method of capable of manufacturing the metal porous body that does not perform plating and easily controls the diameter and number of pores.SOLUTION: A metal porous body having continuous cores and fine pores has a bubble point of 180 μm or less and an average flow diameter or average pore diameter of 60 μm or less. A method for manufacturing the metal porous body includes: a kneading step of kneading a composition comprising a metal fine powder, water-coagulable polyurethane, a solvent, and a granular material of a water-soluble inorganic salt; a defoaming and molding step of defoaming and molding the obtained kneaded mixture; a coagulation and elution step of adding the molded material into water to coagulate it and eluting the formed inorganic salt into the water to remove it; and a sintering step of performing removal of the solvent and sintering.
【課題】気孔径が小さくかつ連続気孔の金属多孔質体、及び前記金属多孔質体を製造できる方法であって、メッキを行わず、かつ気孔径や気孔数のコントロールが容易な方法を提供する。【解決手段】連続気孔の多孔質体であって、バブルポイントが１８０μｍ以下、平均流量径又は平均細孔径が６０μｍ以下であることを特徴とする微細気孔の金属多孔質体、並びに金属微粉末、水凝固性ポリウレタン、溶剤及び水溶性の無機塩の粉粒体を含む配合物を混練する混練工程、得られた混練物を脱泡し、成形する脱泡成形工程、成形物を、水中に投入して、凝固させるとともに形成された前記無機塩を水に溶出させて除去する凝固溶出工程、及び脱媒、焼結する焼結工程、を有することを特徴とする金属多孔質体の製造方法。【選択図】図１ |
