使用Strontium fluoride is transparent to light in the wavelengths from the vacuum UV (150 nm) to the near IR (11 mm). Its optical properties are intermediate to CaF2 and BaF2. Strontium fluoride is used as an optical material for a small range of special applications, for example, as an optical coating on lenses and also as a thermoluminescent dosimeter crystal. Another use is as a carrier of the 90Sr radioisotope in thermoelectric generators. SrF2 is also used as a single crystal for lasers.
製造方法Strontium fluoride is synthesized by the fluorination of strontium dichloride, or by action of hydrofluoric acid on strontium carbonate:SrCl2 (aq)+ F2 (gas)→SrF2 (solid)+ Cl2 (gas)SrCO3+ 2HF→SrF2+ CO2+H2ONote that the first reaction depends upon the insolubility of SrF2 in water. Strontium fluoride is a water-insoluble source for use in oxygen-sensitive applications, such as metal production since it in nonhygroscopic.

化学的特性Strontium fluoride, also called strontium difluoride and strontium(II) fluoride, is a fluoride of strontium. It is a stable brittle white crystalline solid. It forms face-centered cubic crystals, with structure of calcium fluoride. It is almost insoluble in water. Strontium fluoride is prepared by reaction of strontium chloride with fluorine gas, by action of hydrofluoric acid on strontium carbonate, or by addition of potassium chloride to strontium chloride solution. It irritates eyes and skin, and is harmful when inhaled or ingested.
