The phase diagram of the NaF–SrF2 system was studied by thermal analysis and X-ray powder diffraction analysis with the determination of the chemical composition. The system was found to be of the eutectic type. The eutectic co-ordinates are 853 ◦C, 32 mol % SrF2. A narrow range of the existence of solid solution Sr1−xNaxF2−x was established. The NaF solubility reaches a maximal value of x = 0.035 at eutectic temperature. The solubility of KF in SrF2 is very low.
