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 ¦Ìm) 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
One of the uses of strontium fluoride is as a carrier of
strontium-90 radioisotope in radioisotope thermoelectric generators.
