Strontium fluoride is prepared by reaction of strontium chloride with fluorine gas, or by action of hydrofluoric acid on strontium carbonate. It irritates eyes and skin, and is harmful when inhaled or ingested.
Strontium fluoride is used as an optical material transparent from vacuum ultraviolet (150 nm) to infrared (11 µm) for a small range of special applications. Its optical properties are intermediate to calcium fluoride and barium fluoride. It is also used as an optical coating on lenses.
Strontium fluoride can be used as a thermoluminescent dosimeter crystal.
Similar to CaF2 and BaF2, SrF2 displays superionic conductivity at elevated temperatures.
