Strontium carbonate is an important industrial raw material with a wide range of uses. It is a carbonate mineral, belonging to the aragonite group, which is relatively rare and occurs in limestone or marlstone in the form of veins. In nature, it mostly exists in the form of mineral rhodochrosite and strontite, coexisting with barium carbonate, barite, calcite, celestite, fluorite and sulfide, odorless and tasteless, mostly white fine powder or colorless rhombic crystal, or gray, yellow-white, green or brown when infected by impurities. Strontium carbonate crystal is needle-shaped, and its aggregate is mostly granular, columnar, and radioactive needles. Its appearance is colorless, white, green-yellow, with transparent to translucent glass luster, fracture oil luster, brittle, and weak light blue light under the cathode ray. Strontium carbonate is stable, insoluble in water, slightly soluble in ammonia, ammonium carbonate and carbon dioxide saturated aqueous solution, and insoluble in alcohol. In addition, strontium carbonate is also an important raw material for celestite, a rare mineral source.
Strontium Carbonate is a very useful chemical compound and can be used in different ways industrially. Its main industrial applications include:
• It is most commonly used as an inexpensive colorant in fireworks.
• It is utilized to absorb electrons produced by the cathode in color television receivers (CTVs).
• It is commonly used in the ceramics industry as an ingredient in glazes.
• It is also used to make strontium ferrites, which are permanent magnets found in loudspeakers and door magnets.
• It is used to make iridescent glass, luminous paint, strontium oxide, and strontium salts, as well as in sugar refinement for the manufacture of some medications.
• It is used as the raw material of color picture tube glass bulbs.
• It is used in the metallurgy of certain metallic oxides.
• It is used for making some superconductors, like BSCCO.
• As a weak Lewis base, it can be used to produce different strontium compounds by using the corresponding acid.
As an important industrial raw material, strontium carbonate is widely used in the production of picture tubes, monitors, industrial monitors, electronic components, etc.At the same time, strontium carbonate is also the main raw material for the preparation of metallic strontium and various strontium salts. In addition, strontium carbonate can also be used in the production of fireworks, fluorescent glass, signal bombs, paper making, medicine, analytical reagents, sugar refining, zinc metal electrolyte refining, strontium salt pigment manufacturing, etc. With the increasing demand for high-purity strontium carbonate, such as large-screen color TV sets, color displays for computers and high-performance magnetic materials, etc. The production of strontium products in Japan, the United States, Germany and other developed countries has declined year by year due to the depletion of mineral veins, rising energy costs and environmental pollution. So far, the application market of strontium carbonate can be seen.
