Description
Io=io × A (1)
1.A対するBの比が約5.15であって、組成がLa−Ce−Pr−Nd−Ni−Co−Mn−Alの合金を溶融/鋳造し、それから粉体を形成することにより出発合金を調製した。500gの粉体を110℃で1時間、60重量%KOH中でエッチングし、濾過して水洗した。この粉体を塩化ニッケルから得られる8重量%ニッケルと結合させて、30%KOH中で110℃で2時間攪拌を持続し、濾過し、水洗した。調製した材料は次いで負極に形成された。
材料を磁化率試験用に調製した。実施例1の初期合金から調製された粉体を用いて、五つの試料を調製した。第一の試料は、調製のままでエッチングされていない材料である。第二の材料は、110℃で1時間、60%KOHと混合させた。第三の材料は、110℃で2時間、60%KOHと混合させた。第四の材料は、110℃で1時間、60%KOHと混合させ、濾過し水洗した後、更に110℃で1時間、30%KOHで処理した。第5の材料は、少なくとも部分的に触媒を覆う金属を有し、上の実施例1の1.で記述したように調製した。結果は表1に記載されている。
