Nickeline or niccolite is a mineral consisting of nickel arsenide (NiAs) containing 43.9% nickel and 56.1% arsenic. Small quantities of sulfur, iron and cobalt are usually present, and sometimes the arsenic is largely replaced by antimony. This last forms an isomorphous series with breithauptite (nickel antimonide). == Etymology and history == When, in the medieval German Erzgebirge, or Ore Mountains, a red mineral resembling copper-ore was found, the miners looking for copper could extract none from it, as it contains none; worse yet, the ore also sickened them. They blamed a mischievous sprite of German mythology, Nickel (similar to ''Old Nick'') for besetting the copper (German: Kupfer).〔''Chambers Twentieth Century Dictionary'', p888, W&R Chambers Ltd, 1977.〕 This German equivalent of "copper-nickel" was used as early as 1694 (other old German synonyms are ''Rotnickelkies'' and ''Arsennickel''). In 1751, Baron Axel Fredrik Cronstedt was attempting to extract copper from kupfernickel mineral, and obtained instead a white metal that he called after the spirit, nickel. In modern German, Kupfernickel and Kupfer-Nickel designates the alloy Cupronickel. The names subsequently given to the ore, ''nickeline'' from F. S. Beudant, 1832, and ''niccolite,'' from J. D. Dana, 1868, refer to the presence of nickel; in Latin, ''niccolum.'' In 1971, the International Mineralogical Association recommended use of the name nickeline rather than niccolite. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「nickeline」の詳細全文を読む スポンサード リンク
