|Section2= |Section7= |Section8= }} Rubidium fluoride (RbF) is the fluoride salt of rubidium. It is a cubic crystal with rock-salt structure. There are several methods for synthesising rubidium fluoride. One involves reacting rubidium hydroxide with hydrofluoric acid: :RbOH + HF → RbF + H2O Another method is to neutralize rubidium carbonate with hydrofluoric acid: :Rb2CO3 + 2HF → 2RbF + H2O + CO2 Another possible method is to react rubidium hydroxide with ammonium fluoride: :RbOH + NH4F → RbF + H2O + NH3 The least used method due to expense of rubidium metal is to react it directly with fluorine gas, as rubidium reacts violently with halogens: :2Rb + F2 → 2RbF ==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「Rubidium fluoride」の詳細全文を読む スポンサード リンク
