The fluoride minerals containing essential yttrium include tveitite-(Y) (Y,Na)6Ca6Ca6F42 and gagarinite-(Y) NaCaY(F,Cl)6. Sometimes mineral fluorite contains admixtures of yttrium. ==Synthesis== YF3 can be produced by reacting fluorine with yttria or yttrium hydroxide with hydrofluoric acid. :Y(OH)3 + 3HF → YF3 + 3H2O 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「Yttrium(III) fluoride」の詳細全文を読む スポンサード リンク
