Description
Pd99モル%、V1モル%なる組成の合金溶湯からインゴットを得て、これを圧延して厚さ500μm、直径12mmのPd−1モル%Cr水素分離膜を製造した。
膜組成を
Pd−1モル%Nb(実施例2)
Pd-1モル%Ta(実施例3)
Pd-1モル%Cr(実施例4)
Pd-1モル%Mo(実施例5)
Pd−1モル%W(実施例6)
Pd−0.1モル%W(実施例7)
Pd−0.01モル%W(実施例8)
Pd−20モル%Ag−1モル%W(実施例9)
純Pd(比較例1)
Pd−25モル%Ag(比較例2)
としたこと以外は実施例1と同様にして水素分離膜を製造し、実施例1と同様にして、実施例2,3、比較例1,2について外因飛来微粒子に対する耐久性試験を行った。図2〜8にこの耐久性試験後の実施例2〜8の各サンプル表面のSEM撮像を示す。
実施例1〜8の水素分離膜は、図1〜8に示される通り、外因飛来微粒子に対する耐久性にも優れる。図示はされていないが、実施例9の水素分離膜も、膜成分のFe粒子側への急速拡散は観察されず、カーケンダルボイドは発生せず、外因飛来微粒子に対する耐久性に優れていた。これに対し、比較例1,2では、図9,10の通り、鉄微粒子の周囲にカーケンダルボイドが発生しており、外因飛来微粒子に対する耐久性に劣る。
実施例4のPd−1モル%Crの水素分離膜を図12に示す試験用モジュール1にセットして水素透過速度を測定した。
なお、本出願は、2011年3月7日付で出願された日本特許出願(特願2011−048582)に基づいており、その全体が引用により援用される。
