Strontium iodide (SrI2) is a salt of strontium and iodine. It is an ionic, water-soluble, and deliquescent compound that can be used in medicine as a substitute for potassium iodide . It is also used as a scintillation gamma radiation detector, typically doped with europium, due to its optical clarity, relatively high density, high effective atomic number (Z=48), and high scintillation light yield.
Strontium iodide Wikipedia
Strontium iodide can be prepared by reacting strontium carbonate with hydroiodic acid:
+ 2 HI → SrI2
O + CO2
Strontium iodide yellows when exposed to air. At high temperatures (when in the presence of air) strontium iodide completely decomposes to form strontium oxide and free iodine.
