Nickel 鎳

鎳的歷史和鈷的歷史相似，古人早已知道使用鎳的合金——白銅。1751 年，瑞典的礦物學家克朗斯塔特（A.F.Cronstedt）取“尼客爾銅”（Kupfer－nickel）即“假銅”（現名鎳的砷化物礦，又叫紅砷鎳礦）表面風化后的 晶粒與木炭共熱，還原出一種白色金屬，其性質與銅不同，后來他仔細研究 了它的物理、化學性質后，確認是一種新元素。與鈷的命名類似，礦工們對德國的銀礦山上另一種同類礦石也很討厭，它曾使礦工們長期受累，他們稱它為 Kupfer-nickel（“假銅”、“魔鬼的 銅”之意）。克朗斯塔特采用縮略詞“Nickel”（即“小鬼”之意）命名新金屬，漢語譯名稱為“鎳”。

The element nickel was named in 1754 by the Swedish mineralogist Axel von Cronstedt. The word he chose was a truncated form of kupfernickel, a term formerly used by German miners for niccolite, a nickle-bearing ore. This meant literally ‘copperdemon’, an allusion probably to the fact that niccolite looks as though it contains copper, but does not. The -nickel part of the term represents a pet form of the name Nikolaus, perhaps chosen for its resemblance to German nix ‘water-sprite’. Nickel was first used for a US five-cent coin (made of a copper and nickel alloy) in the 1880s.
