Mô tả

Rubidium fluoride (RbF) is the fluoride salt of rubidium. It is an octahedral crystal.

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:

Rb2(CO3) + 2HF → 2RbF + H2O + CO2

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
