Uses

There are no major uses for strontium chloride, though it can be used to prepare less common compounds of strontium, and may be useful in reducing gum sensitivity, and is known as Elecol for this purpose. Certain toothpastes such as Sensodyne are called "strontium chloride toothpastes," although most now use potassium nitrate instead (with the exception of Sensodyne original). Like barium chloride it can be used to test for sulfate ion, though not at such low concentration, since strontium sulfate is more soluble than barium sulfate. In inorganic chemistry, a sulfate (IUPAC-recommended spelling; also sulphate in British English) is a salt of sulfuric acid. ... Celestite (SrSO4) is a mineral consisting of strontium sulfate. ... Granulated Barium Sulfate Barium sulfate (or barium sulphate) is the white crystalline solid with the formula BaSO4. ...

Strontium chloride is occasionally used as a flame coloring agent (red) in pyrotechnics, and in small quantities in glass making and metallurgy. It is added to some toothpastes to reduce periodontal disease, and is used in homeopathic medicine under the name of strontium chlorii. Pyrotechnics are used in the entertainment industry The band Rammsteins stage acts centers largely around pyrotechnics Pyrotechnics is a field of study often thought synonymous with the manufacture of fireworks, but more accurately it has a wider scope that includes items for military and industrial uses. ...
