Strontium carbonate (SrCO3) is the carbonate salt of strontium that has the appearance of a white or grey powder.
Strontium carbonateoccurs in nature as the mineral strontianite.
Chemical properties
Strontium carbonate is a white, odorless, tasteless powder. Being a carbonate, it is a weak base and therefore is reactive with acids.
Strontium carbonateis otherwise stable and safe to work with.
Strontium carbonateis practically insoluble in water (1 part in 100,000).
The solubility is increased significantly if the water is saturated with carbon dioxide, to 1 part in 1,000. Strontium carbonateis soluble in dilute acids.
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 celestine, a mineral form of strontium sulfate (SrSO4).
In the "black ash" process, celesite is roasted with coke at 110–1300 °C to form strontium sulfide.
The sulfate is reduced, leaving the sulfide:
SrSO4 + 2 C → SrS + 2 CO2
A mixture of strontium sulfide with either carbon dioxide gas or sodium carbonate then leads to formation of a precipitate of strontium carbonate.
SrS + H2O + CO2 → SrCO3 + H2S
SrS + Na2CO3 → SrCO3 + Na2S
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.
This material is mixed with hydrochloric acid, which dissolves the strontium carbonate to form a solution of strontium chloride.
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 colorant in fireworks.
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 hygroscopic.
Its ability to neutralize acid is also very helpful in pyrotechnics.
Another similar application is in road flares.
Strontium carbonate is used for electronic applications.
Strontium carbonateis used for manufacturing color television receivers (CTVs) to absorb electrons resulting from the cathode.

Strontium carbonate is also used for making some superconductors such as BSCCO and also for electroluminescent materials where it is first calcined into SrO and then mixed with sulfur to make SrS:x where x is typically europium.
This is the "blue/green" phosphor which is sensitive to frequency and changes from lime green to blue.
Other dopants can also be used such as gallium, or yttrium to get a yellow/orange glow instead.
Because of its status as a weak Lewis base, strontium carbonate can be used to produce many different strontium compounds by simple use of the corresponding acid.
Microbial precipitation
The cyanobacteria Calothrix, Synechococcus and Gloeocapsa can precipitate strontian calcite in groundwater.
The strontium exists as strontianite in solid solution within the host calcite with the strontium content of up to one percent.
Strontium carbonate (SrCO3) belongs to the carbonate salt of strontium, which is found in nature as the mineral strontianite.
Strontium carbonate can be applied in a variety of industries.
At present, strontium carbonates are commonly being applied as an inexpensive colorant in pyrotechnics since strontium and its salts produce a crimson read flame.
Strontium carbonate, in general, is preferred in fireworks, compared with other strontium salts due to its inexpensive cost, nonhygroscopic property, and ability to neutralize acid.
Strontium carbonate can also be used as road flares and for preparing iridescent glass, luminous paints, strontium oxide or strontium salts and in refining sugar and certain drugs.
Strontium carbonate is also recommended as a substitute for barium to produce matte glazes.
Besides, its applications involves in ceramics industry, where it serves as an ingredient in glazes, and in electric products, where it is used for the production of strontium ferrites to produce permanent magnets for loudspeakers and door magnets.
Strontium carbonate is also used for manufacturing some superconductors such as BSCCO and also for electroluminescent materials.
Production Methods
Strontium carbonate occurs in nature as strontianite and can be mined from its deposit.
Strontium carbonate is, however, usually made from the mineral celestite.
Celestite is fused with sodium carbonate at elevated temperatures or boiled with a solution of ammonium carbonate:

General description
Strontium carbonate is insoluble in water.
Strontium carbonate is used predominantly in producing other strontium salts.
Application
Strontium carbonate is used to prepare:
Barium strontium titanate
Barium strontium titanate thin films
Strontium carbonate may be used to prepare europium doped di-strontium magnesium di-silicate phosphor.
Strontium carbonate is used in pyrotechnics, ceramic ferrites, inexpensive fireworks colorant.
Strontium Carbonate is a water insoluble Strontium source that can easily be converted to other Strontium compounds, such as the oxide by heating (calcination).
Carbonate compounds also give off carbon dioxide when treated with dilute acids.
Strontium Carbonate is generally immediately available in most volumes.
Ultra high purity and high purity compositions improve both optical quality and usefulness as scientific standards.
Nanoscale elemental powders and suspensions, as alternative high surface area forms, may be considered.
American Elements produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia) and follows applicable ASTM testing standards.
Typical and custom packaging is available.
Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.
Strontium carbonate (SrCO3) was formerly used in large quantities in the manufacturing of CRT TVs (CRT = cathode-ray tubes) as strontium carbonate together with other compounds absorbs and reduces significantly (to almost zero) the X-rays generated from the television tubes.
Nowadays, modern flat-panel devices have almost completely replaced these tubes.
Currently, strontium carbonates are being used in pyrotechnics as colour-producing components – strontium produces a crimson red flame.
The Latin term “Strontium carbonicum” refers to the homeopathic application of this material which is used to treat osteoarthritis and cerebral sclerosis.
How can I come into contact with this material?
Strontium salts are used in fireworks to produce crimson red flames after ignition and it is not possible to get into direct contact with airborne strontium carbonate nanoparticles during the burning process.
Homeopathic administered strontium carbonate could be considered as a targeted approach for medical purposes but it is not clear if the medical products contain micro- or nano-scaled strontium carbonate or even a mixture of both.
Is there any risk from this material to humans and the environment?
Little information exists on the effects of strontium carbonate nanoparticles on humans or the environment.
This may be due to the relatively small number of applications for this material.
Laboratory studies have shown that different cell types can take up strontium carbonate nanoparticles and high doses may lead to cell death.
However, no harmful effects of strontium carbonate nanoparticles have been found in whole animal studies.
Regarding the environmental behaviour of strontium carbonate nanoparticles, there are currently no data available.
Strontium Carbonate is a very slightly soluble source of SrO used in glazes.
There is disagreement about when it decomposes (data sheets vary from 1075-1100C, one even indicates 1340C) as follows:
SrCO3 -> SrO + CO2
The 'Ceramic Industry Materials Handbook' states that it starts to disassociate as early as 800C in a purely oxidizing atmosphere, whereas a CO2 atmosphere might delay break-down until around 1220C.
Wikipedia says it melts and decomposes at the same time, 1100C.
Strontium carbonate is often recommended as a substitute for barium to produce matte glazes.
Use about 75% as much and test first to make sure color response is the same.
However strontium is not a substitute for barium as a precipitator of soluble salts in clay bodies because it combines with SO4-- ions in the water to form a compound that is not nearly as insoluble as BaSO4.
Viscous zirconium silicate glazes can be smoothed with the addition of strontium carbonate.
Strontium is considered a safe material. Some people confuse SrO with Strontium 90, an isotope released from atomic reactions; they are not the same thing.
As noted, strontium carbonate produces gases as it decomposes and these can cause pinholes or blisters in glazes (if they are being generated into a glaze melt having a viscosity and surface tension that is unable to pass them or heal over properly as they escape or one that simply does not have time because of quick cooling).
There are strontium frits available (e.g. Fusion F-581 has 39% SrO) and incorporating one of them to source it instead of raw strontium carbonate (a classic job for glaze chemistry calculations).
The resultant glaze will be more fusible and will have better clarity and fewer defects.
Strontium frits have become much more common of late and are useful to producing brilliant transparent glazes without having a high expansion (like those based on Na2O and K2O).
Please read the information about the oxide SrO to fully appreciate the value of SrO (especially when sourced from frits), not just as alternatives to this material, but as excellent ways to produce brilliant glazes.
Some pottery glazes have such high strontium carbonate percentages that a frit cannot supply the needed SrO.
These are, of course, special purpose formulations, having an SrO content that exceeds (or far exceeds) normal target or limit formulas.
According to the Wikipedia article, while it does have a low solubility, this increases dramatically with temperature (about 50 times greater at 100C verses room temperature) and up to 100 times greater in the presence of CO2 in the slurry.
Both of these factors play in glaze slurries (they can contain other carbonates that are disassociating) and thus indicate the potential to flocculate or deflocculate them.

Celestite is converted to SrCO3, the common commercial form of strontium.
The black ash method (alternatively known as the calcining method) and the soda method (also known as direct conversion) are the two most common recovery techniques for strontium.
The black ash method produces chemical grade strontium carbonates, which are 98% strontium carbonate and 2% byproducts and impurities.
The soda ash method produces technical grade strontium carbonates, containing at least 97% strontium carbonate.
The black ash method is the preferred means of strontium carbonate production because it yields a highergrade product.

Strontium carbonate is a weak base being a carbonate and is thus volatile with acids. Working with these is otherwise secure and safe.
Strontium carbonate is essentially insoluble in water (1 in 100,000 parts).
If the water is polluted with carbon dioxide, the solubility would increase greatly, to 1 element in 1,000. Soluble in dissolved acids.
Strontium carbonate is applicable in a number of industries.
Strontium carbonate is very insoluble in water; it dissolves in acids, e.g. in hydrochloric acid, producing the following carbon dioxide:
SrCO3 + 2 HCl → SrCl2 + H2O + CO2
Strontium is in the Alkaline Earth Metals group.
Such as calcium, which is in the same category, it is non-toxic.
