It is used as an oxidizer and colorant in fireworks. == Preparation== Strontium nitrate is typically generated by the reaction of [[nitric acid]] on [[strontium carbonate]].<ref name=Ward>Ward, R.; Osterheld, R.

The primary difference strontium nitrate has over the other salts is the fact it is an oxidizer. This provides two uses in pyrotechnics. Solutions of Sr(NO<sub>3</sub>)<sub>2</sub> reacts with [[sulfuric acid]] to precipitate [[Strontium sulfate|SrSO<sub>4</sub>]], a precursor to the [[phosphor]] [[strontium sulfide]].<ref name=Ward/> == Health warning == If strontium nitrate is heated to the point of decomposition it will produce [[strontium oxide]] and release toxic [[nitrogen dioxide]] gas. ==References== <references/> [[Category:Nitrates]] [[Category:Strontium compounds]] [[Category:Inorganic compound stubs]] [[Category:Pyrotechnic oxidizers]] [[Category:Pyrotechnic colorants]] [[ar:نترات سترونتيوم]] [[de:Strontiumnitrat]] [[fr:nitrate de strontium]] [[no:Strontiumnitrat]] [[nn:Strontiumnitrat]] [[pl:Azotan(V) strontu]]
