Strontium iodide
Template:Chembox Strontium iodide is an inorganic compound with the chemical formula Template:Chem2. It is a salt of strontium and iodine. It forms a hexahydrate Template:Chem2. It is an ionic, water-soluble, and deliquescent compound that can be used in medicine as a substitute for potassium iodide.[1] 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.[2] In recent years, europium-doped strontium iodide (Template:Chem2:Template:Chem2) has emerged as a promising scintillation material for gamma-ray spectroscopy with extremely high light yield and proportional response, exceeding that of the widely used high performance commercial scintillator Template:Chem2:Template:Chem2. Large diameter Template:Chem2 crystals can be grown reliably using vertical Bridgman technique [3] and are being commercialized by several companies.[4][5]
Reactions
Strontium iodide can be prepared by reacting strontium carbonate with hydroiodic acid:
Strontium iodide forms a white powder that slowly changes to a yellowish colour when exposed to air. At high temperatures (in the presence of air) strontium iodide completely decomposes to form strontium oxide and free iodine.[6]
