What is Strontium Carbonate used for?
Strontium Carbonate (SrCO3) can be applied in a variety of industries, such as Display tube of color TV, ferrite magnetitum, fireworks, signal flare, metallurgy, optical lens, cathode material for vacuum tube, pottery glaze, semi-conductor, iron remover for sodium hydroxide, reference material. 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.
