Strontium carbonate is used for electronic applications. It is used for manufacturing color television receivers to absorb electrons resulting from the cathode. [5] It is used in the preparation of iridescent glass, luminous paint, strontium oxide, and strontium salts and in refining sugar and certain drugs.

Strontium carbonate: SrCO 3: Common. Produces good red. Slows burning of compositions, decomposes yielding carbon dioxide. Fire retardant in gunpowders. Inexpensive, non-hygroscopic, neutralizes acids. Superior over strontium oxalate in absence of magnesium. Red Strontium oxalate: SrC 2 O 4: Decomposes yielding carbon dioxide and carbon monoxide.
Strontium carbonate is a recycled coreactant in this process. Strontium carbonate is calcined with carbon in the presence of steam to form strontium hydroxide. The strontium and carbon dioxide formed are rejoined later in the process, forming strontium carbonate once again. [1] SrCO 3 + C + H 2 O + O 2 = Sr(OH) 2 + 2 CO 2
Strontium oxide or strontia, SrO, is formed when strontium reacts with oxygen. Burning strontium in air results in a mixture of strontium oxide and strontium nitride. It also forms from the decomposition of strontium carbonate SrCO 3. It is a strongly basic oxide.
Strontium carbonate is used as a fire retardant in some gunpowders. Flame suppressants. Potassium nitrate and potassium sulfate are commonly used. Opacifiers. Some solid rocket propellants have problems with radiative heat transfer through the material, which may lead to explosion. Carbon black and graphite are often used to inhibit this effect.
Strontium carbonate and other strontium salts are added to fireworks to give a deep red colour. [70] This same effect identifies strontium cations in the flame test. Fireworks consume about 5% of the world's production. [56] Strontium carbonate is used in the manufacturing of hard ferrite magnets. [71] [72]
