It was invented in 1910 by Matthew A. Hunter, a chemist born in New Zealand, who worked in the US.〔 M. A. Hunter "Metallic Titanium" J. Am. Chem. Soc. 1910, pp 330–336. 〕 The process involved reducing titanium tetrachloride (TiCl4) with sodium (Na) in a steel bomb at 700–800 °C. :TiCl4 + 4 Na → 4 NaCl + Ti Prior to the Hunter process, all efforts to produce Ti metal afforded highly impure material, often titanium nitride (which resembles a metal). The Hunter process was replaced by the more economical Kroll process in the 1940s. In the Kroll Process, TiCl4 is reduced by magnesium.〔Heinz Sibum, Volker Günther, Oskar Roidl, Fathi Habashi, Hans Uwe Wolf, "Titanium, Titanium Alloys, and Titanium Compounds" in Ullmann's Encyclopedia of Industrial Chemistry 2005, Wiley-VCH, Weinheim. 〕 ==References== 〔 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「Hunter 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.
