This colorless gas is formed by reacting germanium with fluorine or germanium dioxide (GeO2) with hydrofluoric acid (HF). Germanium difluoride can be synthesized by reacting germanium tetrafluoride with powdered germanium at 150–300 °C.〔 ==Synthesis== Germanium tetrafluoride can be prepared by reaction of germanium with fluorine or hydrogen fluoride: : Ge + 2 F2 → GeF4 It is also formed during the thermal decomposition of a complex salt, Ba():〔 : Ba(GeF6) → GeF4 + BaF2 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「germanium tetrafluoride」の詳細全文を読む スポンサード リンク
