'''Strontium sulfate''' (SrSO<sub>4</sub>) is the ] salt of ]. It is a white crystalline powder and occurs in nature as the mineral ]. It is poorly soluble in water to the extent of 1 part in 8,800. It is more soluble in dilute ] and ] and appreciably soluble in alkali ] solutions (e.g. ]). |
|
|
|
|
|
==Structure== |
|
|
Strontium sulfate is a polymeric material, isostructural with ]. Crystallized strontium sulfate is utilized by a small group of ]n ], called the ], as a main constituent of their ]. |
|
|
|
|
|
==Applications and chemistry== |
|
|
Strontium sulfate is of interest as a naturally occurring precursor to other strontium compounds, which are more useful. In industry it is converted to ] for use as ceramic precursor and ] for use in pyrotechnics.<ref>J. Paul MacMillan, Jai Won Park, Rolf Gerstenberg, Heinz Wagner, Karl Köhler, Peter Wallbrecht “Strontium and Strontium Compounds” in Ullmann's Encyclopedia of Industrial Chemistry 2002, Wiley-VCH, Weinheim. {{doi|10.1002/14356007.a25_321}}.</ref> |

The low aqueous solubility of strontium sulfate can lead to ] in processes where these ions meet. For example, it can form on surfaces of equipment in underground ]s depending on the ] conditions.<ref>{{Cite journal|url=https://www.onepetro.org/journal-paper/SPE-9625-PA|doi = 10.2118/9625-PA|title = A Study of Solubility of Strontium Sulfate|year = 1983|last1 = Jacques|first1 = Donald F.|last2 = Bourland|first2 = Brent I.|journal = Society of Petroleum Engineers Journal|volume = 23|issue = 2|pages = 292–300}}</ref><ref>{{cite journal | doi=10.1520/JAI100958 | title=Prediction of Strontium Sulfate Scale Formation in Oilfield Environment | year=2007 | last1=Dean | first1=S.
