Radium fluoride (RaF ₂ ) is a white, cubic crystalline, water-insoluble solid with a melting point of 1327 ° C. The crystal structure is that of calcium fluoride s similar.

Radium fluoride by passing hydrogen fluoride gas over metallic radium synthesized:

{\ displaystyle {\ ce {Ra + 2 HF -> RaF2 + H2}}}

The enthalpy of formation of RaF ₂ is Δ H _f = −1206 kJ / mol.
