Poison as a soluble fluoride. When heated to decomposition it emits toxic fumes of RbzO and F-. See also RUBIDIUM and FLUORIDES. |
| Hazard Information | Back Directory | [Hazard]
Strong irritant to tissue.
| [Chemical Properties]
Rubidium fluoride is a colorless cubic crystal. It is highly toxic and soluble in water and dilute hydrofluoric acid solutions, but insoluble in ethanol, diethyl ether, and ammonia. Its hydrofluoric acid solution exhibits strong acidity and can corrode glass.
 | [Uses]
As raw materials for preparation of rubidium metal and various rubidium salts, for the manufacturing of catalyst and for the manufacturing of high energy density micro cells and crystal scintillation counters. | [Preparation]
Rubidium fluoride is produced by concentrating the reaction product of rubidium carbonate with hydrofluoric acid. | [Reactions]
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 |
