摘要

The possibility of the hydrothermal crystal synthesis/growth of the SrF2-solid solutions by spontaneous nucleation is studied in the system SrF2LaF3. The lattice parameters of the solid solutions synthesized at 750°C by solid state reaction for 23 days in vacuum, or by hydrothermal reaction for 1 day under 100 MPa in 10 wt% LiCl solution, were identical. The composition of the Sr1-sLaxF2+x crystals could be controlled by the starting composition. Single cubic crystals (x = 0·4) about 0·2 mm in size were grown at 650°C for 7 days under 100 MPa in 10 wt% LiCl aqueous solution from the composition containing 50 wt% SrF2. Single hexagonal plate-like cyrstals of LaF3-solid solution were also obtained, being about 0·2 mm in size. Hydroxyl ions (OH-) were not detected in the products by infrared spectroscopy.
