'''Strontium carbonate''' (SrCO<sub>3</sub>) is the carbonate salt of ] that has the appearance of a white or grey powder. It occurs in nature as the mineral ].

== Chemical properties ==
Strontium carbonate is a white, odorless, tasteless ]. Being a ], it is a weak ] and therefore is reactive with ]s. It is otherwise stable and safe to work with. It is practically insoluble in ] (0.0001&nbsp;g per 100&nbsp;ml). The ] is increased significantly if the water is saturated with ], to 0.1&nbsp;g per 100&nbsp;ml.

== Preparation ==
Other than the natural occurrence as a mineral, strontium carbonate is prepared synthetically in one of two processes, both of which start with naturally occurring ], a mineral form of ] (SrSO<sub>4</sub>). In the "black ash" process, celesite is ] with ] at 1100–1300&nbsp;°C to form ].<ref name=hydrometallurgy>{{cite journal |journal= Hydrometallurgy |volume= 84 |issue= 3–4 |year= 2006 |pages= 239–246 |title= Dissolution kinetics of celestite (SrSO<sub>4</sub>) in HCl solution with BaCl<sub>2</sub> |first1= Salih |last1= Aydoğan |first2= Murat |last2= Erdemoğlu |first3= Ali |last3= Aras |first4= Gökhan |last4= Uçar |first5= Alper |last5= Özkan |doi= 10.1016/j.hydromet.2006.06.001 |bibcode= 2006HydMe..84..239A}}</ref> The sulfate is ], leaving the sulfide:

:SrSO<sub>4</sub> + 2 C → SrS + 2 CO<sub>2</sub>

A mixture of strontium sulfide with either ] gas or ] then leads to formation of a ] of strontium carbonate.<ref name=Ullmann>{{Ullmann|first1= J.

:SrS + H<sub>2</sub>O + CO<sub>2</sub> → SrCO<sub>3</sub> + H<sub>2</sub>S
:SrS + Na<sub>2</sub>CO<sub>3</sub> → SrCO<sub>3</sub> + Na<sub>2</sub>S

In the "direct conversion" or double-decomposition method, a mixture of celesite and sodium carbonate is treated with steam to form strontium carbonate with substantial amounts of undissolved other solids.<ref name=hydrometallurgy/> This material is mixed with ], which dissolves the strontium carbonate to form a solution of ]. Carbon dioxide or sodium carbonate is then used to re-precipitate strontium carbonate, as in the black-ash process.

== Uses ==
].]]
The most common use is as an inexpensive ] in ]s. Strontium and its salts emit a brilliant red color in flame. Unlike other strontium salts, the carbonate salt is generally preferred because of its cost and the fact that it is not ]. Its ability to neutralize acid is also very helpful in pyrotechnics. Another similar application is in ]s.

Strontium carbonate is used for electronic applications. It is used for manufacturing ] receivers to absorb electrons resulting from the ].<ref>{{cite web |url=http://www.primaryinfo.com/strontium-carbonate.htm |title=Strontium Carbonate |website=primaryinfo.com |accessdate=May 31, 2017}}</ref>

It is used in the preparation of ], ], strontium oxide, and strontium salts and in refining sugar and certain drugs.

It is widely used in the ceramics industry as an ingredient in glazes. It acts as a ] and also modifies the color of certain metallic oxides. It has some properties similar to ].

It is also used in the manufacturing of strontium ] for ]s which are used in ]s and door magnets.<ref>{{cite web |url=https://www.stanfordmagnets.com/ceramic-ferrite-magnets.html |title=Ceramic Ferrite Magnets |website=Stanford Magnets |access-date=Oct 7, 2024}}</ref>

Strontium carbonate is also used for making some ]s such as ] and also for electroluminescent materials where it is first calcined into ] and then mixed with ] to make ]:x where x is typically ].{{Citation needed|date=November 2015}} This is the "blue/green" phosphor which is sensitive to ] and changes from lime green to blue.{{Citation needed|date=November 2015}} Other ]s can also be used such as ], or ] to get a yellow/orange glow instead.

Because of its status as a weak ], strontium carbonate can be used to produce many different strontium compounds by simple use of the corresponding acid.

==Microbial precipitation==
The ] '']'', '']'' and '']'' can precipitate strontian ] in ]. The strontium exists as ] in ] within the host calcite with the strontium content of up to one percent.<ref>{{cite book|title=Geomicrobiology, Fifth Edition| author1=Henry Lutz Ehrlich| author2=Dianne K Newman| publisher=CRC Press| date=2009|page=177}}</ref>
