Some Knowledge About Strontium Chloride

2021-12-04

Strontium Chloride, also known as strontium dichloride, is a colorless transparent crystal or granule with a bitter taste. The molecular formula is SrCl2 and the molecular weight is 158.53. Strontium chloride is a raw material for the production of strontium salts and pigments. It is used as a flux for the manufacture of pyrotechnics and electrolysis of metallic sodium, and as a catalyst for organic synthesis.

The production method of strontium chloride:
In the hydrochloric acid method, the lapis lazuli was crushed to 200 meshes, added to the reactor and stirred with water, and then industrial hydrochloric acid was slowly added, and steam was added to stir to remove impurities such as calcium salts. Then decanted and washed to neutrality. Stir the washed slurry with water, then add soda ash, heat it with steam to generate Strontium Carbonate, wash it with water to neutrality, wash away sodium Sulfate and unreacted soda ash, and add hydrochloric acid for acidolysis reaction. End point control solution pH 4~5. Under heating near boiling, 10% dilute sulfuric acid and 30% hydrogen Peroxide are added to remove soluble barium salt and iron. The clarified solution is filtered, concentrated by evaporation to 42-43°, cooled and crystallized, centrifuged, and dried at 220-250°C to obtain anhydrous strontium chloride.

Uses of strontium chloride:

Strontium chloride is occasionally used as a red colorant for fireworks. A small amount of strontium chloride is also added in glass manufacturing and metallurgy. The radioisotope strontium-89 is used to treat bone cancer, usually in the form of strontium chloride. Marine aquariums need a small amount of strontium chloride to provide some plankton to produce exoskeletons. It can also be used to make pyrotechnics, fluxes for electrolysis of sodium metal, and catalysts for organic synthesis.
