Förfarande för framställning av nickelhydroxid |
摘要 |
A process for producing nickel hydroxide from nickel powders, in which the feed nickel powder is directly converted in an aqueous solution containing nitrate and particulate nickel at least at room temperature and a pH in excess of about 6 into nickel hydroxide of a high density. Nickel powders of high surface area, e.g. 0.4 m<2>/g or higher, typically produced by the thermal decomposition of nickel carbonyl, are particularly suitable as feed materials for this process. |
