The solubility in the system SrF2-LaF3 were studied by solid state reaction (1400°, 1300°, 1000° and 750°C) using Pt capsules and hydrothermal reaction (750°, 650° and 500°C) using the 10wt% LiCl or other solutions. Starting samples were (I) mixed and (II) fired samples of SrF2 and LaF3 powders (99.9%). At any temperatures, a linear relation between the composition and the lattice parameter of the solid solutions of each phase (SrF2ss or LaF3ss) could be obtained corresponding to the Vegard's law. The hydrothermal reaction was very effective to accelerate the reactions to reach to the phase equilibria; 1 day by hydrothermal and 23(7+7+9) days by solid state reactions at 750°C. The solubility limits in SrF2ss were 48,48,47,47 and 46 mol% LaF3, and those in LaF3ss were 15,11, 6,4 and 2 mol% SrF2 at 1400°, 1000°,750°,650° and 500°C, respectively by X-ray measurements.
