Nickel 镍

镍的历史和钴的历史相似，古人早已知道使用镍的合金——白铜。1751 年，瑞典的矿物学家克朗斯塔特（A.F.Cronstedt）取“尼客尔铜”（Kupfer－nickel）即“假铜”（现名镍的砷化物矿，又叫红砷镍矿）表面风化后的 晶粒与木炭共热，还原出一种白色金属，其性质与铜不同，后来他仔细研究 了它的物理、化学性质后，确认是一种新元素。与钴的命名类似，矿工们对德国的银矿山上另一种同类矿石也很讨厌，它曾使矿工们长期受累，他们称它为 Kupfer-nickel（“假铜”、“魔鬼的 铜”之意）。克朗斯塔特采用缩略词“Nickel”（即“小鬼”之意）命名新金属，汉语译名称为“镍”。

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.
