Radium fluoride is an inorganic compound with a chemical formula of RaF₂. This salt, like all radium compounds is highly radioactive. It can be coprecipitated with lanthanide fluorides.[2] Radium fluoride has the same crystal form as calcium fluoride (fluorite).

Production

Radium fluoride can be produced by the reaction of radium metal and hydrogen fluoride gas:

Ra + 2 HF → RaF₂ + H₂
