It is a black solid prepared by reduction of V2O5 with hydrogen or carbon monoxide.〔Handbook of Preparative Inorganic Chemistry, 2nd Ed. Edited by G. Brauer, Academic Press, 1963, NY. Vol. 1. p. 1267.〕It is a basic oxide dissolving in acids to give solutions of vanadium(III) complexes.〔 V2O3 has the corundum structure.〔 It is antiferromagnetic with a critical temperature of 160 K. 〔E.M. Page, S.A.Wass (1994),''Vanadium:Inorganic and Coordination chemistry'', Encyclopedia of Inorganic Chemistry, John Wiley & Sons, ISBN 0-471-93620-0〕 At this temperature there is an abrupt change in conductivity from metallic to insulating.〔 Upon exposure to air it gradually converts into indigo-blue V2O4.〔 In nature it occurs as the very rare mineral karelianite. ==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「Vanadium(III) oxide」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.
