It was first isolated in 1878 from an impure sample of erbia by Per Teodor Cleve, who named it ''thulia''. It can be prepared in the laboratory by burning thulium metal in air, or by decomposition of their oxoacid salts, such as thulium nitrate. ==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「Thulium(III) oxide」の詳細全文を読む スポンサード リンク
