Description
本出願は、2016年10月14日に出願された大韓民国特許出願第10−2016−0133352号に基づく優先権の利益を主張し、該当韓国特許出願の文献に開示されたすべての内容は本明細書の一部として組み入れるものとする。
本出願は、金属フォームの製造方法及び金属フォームに関する。
金属成分として、20℃での伝導度が約14.5MS/mであり、相対透磁率が約600程度であるニッケルを使用した。平均粒径が約5〜10μmの範囲内である前記ニッケル粉末を溶媒である水とメチルセルロース(methyl cellulose)及びエチルセルロース(ethyl cellulose)と配合してスラリーを製造した。前記でメチルセルロースの前記水に対する溶解度は、常温で約180mg/mL程度であり、エチルセルロースの前記水に対する溶解度は、常温で約1mg/mL水準である。スラリーの製造時には、ニッケル粉末、水、メチルセルロース及びエチルセルロースの重量割合(ニッケル粉末:水:メチルセルロース:エチルセルロース)を約2.8:2.7:0.3:1にした。前記スラリーを石英プレート上にフィルム形態にコーティングしてグリーン構造体を形成した。引き続き、前記グリーン構造体を約110℃の温度で30分程度乾燥処理した後、コイル形態の誘導加熱器で電磁気場を前記グリーン構造体に印加した。電磁気場は、約350Aの電流を約380kHzの周波数で印加して形成し、電磁気場は、約5分間印加した。電磁気場の印加後に、焼結されたグリーン構造体を水に入れて、超音波(sonication)洗浄してフィルム形態の厚さが約130μm水準であるニッケルシートを製造した。前記製造されたシートの写真は、図1に示した。前記製造されたニッケルシートの気孔度は、約82%水準であり、引張強度は、約3.4MPa程度であった。
金属成分として、平均粒径が約30〜40μmの範囲内である前記ニッケル粉末を使用し、スラリーの製造時には、ニッケル粉末、水、メチルセルロース及びエチルセルロースの重量割合(ニッケル粉末:水:メチルセルロース:エチルセルロース)を約2.8:2.7:0.3:1にしたこと以外は、実施例1と同一の方式でフィルム形態の厚さが約120μm水準であるニッケルシートを製造した。前記製造されたニッケルシートの気孔度は、約81%水準であり、引張強度は、約4.1MPa程度であった。
