Description
Mg+2H2O→Mg(OH)2+H2
内径が約9cmで深さが約4cmの容器に、マグネシム合金AZ31の切り屑(平均径5mm以上)2gと、4℃の純水100gを混合した後、−20℃に冷却して、マグネシム合金の切り屑の一部が上面から飛び出している氷の塊体を得た。これに4℃の純水100gをさらに加え、−20℃に冷却して、マグネシム合金と氷を含む塊体を得た。かき氷機(パール金属株式会社、クールジョイ)を用いて、この塊体を粉砕し、マグネシウム合金の粒子と氷を含有する粉体を得た。プラスチック製ザル内でこの粉体を室温で放置し、水切りをして、マグネシウム合金の粒子(平均径1mm)を得た。
ボールミル処理に代えて以下の加水分解工程を行った点を除いて、実施例1と同様にして水素発生量を測定した。加水分解工程では、20℃の環境下、マグネシウム合金の粒子2gと3%塩化ナトリウム水溶液200mLを容量1000mLのフラスコに入れ、ゴム栓に設けた管から流出したガスを水上置換して、ガスの発生量を測定した。その結果を図2の●で示す。
マグネシウム合金の粒子に代えて、実施例1で使用したマグネシム合金の切り屑を用いた点を除いて、実施例2と同様にして水素発生量を測定した。その結果を図2の○で示す。図2の実施例1、実施例2、および比較例からわかるように、本発明によれば、マグネシム合金の切り屑をそのまま加水分解するときと比べて、より多くの水素が製造できる。
