SURAT CHEMICAL TAG:
Strontium carbonate (SrCO3)(1633-05-2) 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.

Uses:
- The compound, SrCO3, is used in pyrotechnics and ceramic ferrites. It is also used in making iridescent glass for color television tubes. Other uses are in refining sugar and preparing other strontium salts. The most common use is as an inexpensive fireworks colorant. Strontium and its salts emit a brilliant red color in flame. 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. It is used for manufacturing glass colortelevision tubes to absorb X-rays resulting from the bombardment of the cathode rays on the glass enclosure of the cathode-ray gun. SrCO3 is used in the preparation of iridescent glass, strontium oxide or strontium salts and in refining sugar.It is widely used in the ceramics industry as an ingredient in glazes. It acts as a flux and also modifies the color of certain metallic oxides. It is also used in the manufacturing of strontium ferrites for permanent magnets that are used in loudspeakers and door-magnets. Strontium carbonate can be used to produce many different strontium compounds by simply dissolving it in the corresponding acid. Strontium bicarbonate has not been isolated.
