[Description]
Strontium carbonate (SrCO3) belongs to the carbonate salt of strontium, which is found in nature as the mineral strontianite. It 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. It 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. It 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. It 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:
SrSO4 + Na2CO3 → SrCO3 + Na2SO4
SrSO4 + (NH4)2CO3 → SrCO3 + 2NH3 + CO2 + H2O
Strontium carbonate is insoluble in water. It precipitates from the product mixture in the second reaction. If fused with sodium carbonate, the product mixture is leached with water. Insoluble carbonate separates from the watersoluble sodium sulfate.

[Occurrence]
Strontium carbonate occurs in nature as mineral strontianite. The compound is used in pyrotechnics and ceramic ferrites. It also is used in making iridescent glass for color television tubes. Other uses are in refining sugar and preparing other strontium salts. |
[Preparation]
Strontium carbonate occurs in nature as strontianite
and can be mined from its deposit. It is, however,
usually made commercially from the mineral “celestite”.
Celestite is fused with sodium carbonate at elevated
temperatures or boiled with a solution of ammonium
carbonate.Strontium carbonate is insoluble in water. It precipitates
from the product mixture in the second reaction.
If fused with sodium carbonate, the product mixture is
leached with water. Insoluble carbonate separates from
the water-soluble sodium sulfate. |
[Definition]
strontium carbonate: A whitesolid, SrCO3; orthorhombic; r.d. 3.7;decomposes at 1340°C. It occurs naturallyas the mineral strontianite andis prepared industrially by boiling celestine(strontium sulphate) with ammoniumcarbonate. It can also beprepared by passing carbon dioxideover strontium oxide or hydroxide orby passing the gas through a solutionof strontium salt. It is a phosphor,used to coat the glass of cathode-rayscreens, and is also used in the refiningof sugar, as a slagging agent incertain metal furnaces, and to providea red flame in fireworks. |
