Description
本出願は、2013年9月13日出願の米国非仮特許出願第14/026,273号明細書『モリブデンストリップ又はモリブデン含有ストリップの作製方法』に関連し、その優先権の利益を主張し、その内容の全体が全ての目的のために参照によって本明細書に援用される。
700ppmの酸素含有量と30ppm未満の炭素含有量を有するモリブデン金属粉体を得た。約2kgのモリブデン粉体をセルロースバインダーと混ぜ、15分間混合した。混合した粉体をロール圧縮して、0.090インチ(約0.2286cm)の厚さを有するグリーンストリップを生産した。
実施例Iと同様の手順を用いて、別の供給源から得たモリブデン金属粉体をロール圧縮し、仕上げストリップへと処理した。応力除去操作の後の仕上げストリップは、32ppmのO2含有量と5ppmのN2含有量を有した。試料に対する引張り試験の結果を下の表IIに示す。
