Product Description
Strontium chloride is a kind of inorganic salt. It is a common strontium salt. The aqueous solution is weakly acidic (due to the weak hydrolysis of Sr2). Similar to other strontium compounds, strontium chloride is red under flame, so it is used Make red fireworks. Its chemical properties are between barium chloride (more toxic) and calcium chloride
. It is a precursor to other strontium compounds, such as strontium chromate. It is used as a corrosion inhibitor for aluminum. Chromate ions are similar to sulfate ions, and their corresponding precipitation reactions are similar:
Strontium chloride is occasionally used as a red colorant for pyrotechnics. Small amounts of strontium chloride are also added in glassmaking and metallurgy. The radioactive isotope strontium-89 is used to treat bone cancer, usually in the form of strontium chloride. Seawater aquariums need a small amount of strontium chloride to provide some plankton to produce exoskeletons. Can also be used in the manufacture of fireworks, electrolytic metal sodium flux, organic synthesis catalyst. The toxicity of strontium chloride is less than that of barium chloride, which is of low toxicity and slightly irritating. To avoid dust contact eyes, mouth, avoid inhalation.
