Description
Mg 2 Ni粒子とNi粒子とを混練する工程、
Mgの水素化物の粒子を添加して混練する工程、および
Mgの水素化物を脱水素してMgとする工程
を上記順序で行なうことを特徴とする。
A:Mg、B:Cu、A−B:Mg2Cu、A−H:MgH2
A:Al、B:Ni、A−B:Al3Ni、A−H:AlH3
A:Al、B:Cu、A−B:AlCu、 A−H:AlH3
いずれの組み合わせにおいても、水素吸蔵媒体である金属Aよりも、金属間化合物A−Bが低温で水素化開始し、それを金属Bが触媒として促進する。この過程で、金属間化合物A−Bの水素化による発熱で昇温して金属Aの水素化が開始し、その発熱で更に昇温して金属Aの水素化すなわち水素吸蔵が促進されるといメカニズムが働く。
MgH2粉末 :アボガド製、純度99%、平均粒径=数10μm。
Mg2Ni粉末 :日本重化学工業製、純度99%、平均粒径=数10μm。
Ni粉末 :高純度化学製、純度99.9%、平均粒径=数10μm。
上記の各粉末を表1に示した配合組成となるように秤量した。
第二工程として、第一工程後のMg2NiとNi粉末をメカニカルミリングにて混練した。時間は、上記1〜2サイクルの間である。
第三工程として、第二工程終了材に第一工程終了MgH2を添加し混練した。時間は、上記サイクルの積算として最長100時間実施した。
ここで、Mg源として金属Mgではなくて金属間化合物MgH2を用いたのは下記の理由による。
前記のように2段階で混練した後に、1atmの大気圧下で300℃に1hr加熱することにより脱水素して水素化物MgH2を金属Mgにした。
表1の示した各サンプルについて、水素吸蔵試験を行なった。試験条件は下記のとおりであった。
水素吸蔵量は、いわゆるジーベルツ法により予定水素圧からの低下量から算出した。測定温度60℃、圧力10気圧未満で測定した。
吸蔵速度は、圧力低下の時間依存から、飽和量の80%吸蔵までの時間を吸蔵時間として評価した。
表2に示すサンプルについて、水素吸蔵および放出試験を行なった。吸蔵試験条件は前述のとおりであり、放出試験条件は下記のとおりであった。
<水素放出試験条件>
300℃、大気圧下で水上置換法により時間に対する放出ガス量を測定して、放出量および放出速度を求めた。
2 Mg2Ni粒子
3 Ni粒子
10 1次複合粒子(Mg2Ni粒子とNi粒子が密着合体)
100 2次複合粒子(Mg粒子の表面に一次複合粒子が密着固定)
