Below that temperature, the melt would solidify; above that temperature, the metal would start to dissolve in the melt. ==History== The Castner process for production of sodium metal was introduced in 1888 by Hamilton Castner. At that time (prior to the introduction in the same year of the Hall-Héroult process for electrowinning aluminum) the primary use for sodium metal was as a reducing agent to produce aluminum from its purified ores. The Castner process reduced the cost of producing sodium in comparison to the old method of reducing sodium carbonate at high temperature using carbon.〔(Manufacturer and builder / Volume 20, Issue 9, 1888 )〕 This in turn reduced the cost of producing aluminum, although the reduction-by-sodium method still could not compete with Hall-Héroult. The Castner process continued nevertheless due to Castner's finding new markets for sodium. In 1926, however, the Downs cell replaced the Castner process.〔(Caveman Chemistry:Dow Electrochemicals )〕 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「Castner process」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
