Properties and Applications

Properties: Strontium carbonate, whose chemical formula is SrCO₃, is a fine, white powder whose properties are similar to those of calcium carbonate (lime). SrCO₃ is very little soluble in water; it dissolves in acids, for example in hydrochloric acid, developing carbon dioxide as follows: SrCO₃ + 2 HCl -> SrCl₂ + H₂O + CO₂. Strontium is in the group of the alkaline earth metals (2. main group). It is non-toxic just like calcium, which is in the same group. The chemical similarity of strontium and calcium, however, accounts for the fact that the radioactive strontium isotopes that formed during the Chernobyl reactor accident have been able to deposit in the bones to trigger cancer.

 

Applications: Strontium carbonate, among other things, is used for manufacturing ferrite magnets that serve to extract strontium ferrite. Its main application is the production of glass for cathode ray tubes, better known as (color) television tubes. Since strontium carbonate has a relatively large atomic radius, it absorbs the X-radiation that occurs in the tubes. Through addition of SrCO₃ and other compounds, the X-radiation disappears almost completely. It is due to today’s LCD and plasma screens, however, that the production of cathode ray tubes is more and more decreasing. Strontium carbonate is also used in glazings. Pyrotechnics rely on the chromophoric salts of strontium to give flames their crimson color

 

In medicine, strontium was formerly used sometimes to treat schizophrenia. Today, the substance is used as homeopathic “strontium carbonicum” to treat e.g., arthrosis and cerebral sclerosis.

 

Strontium carbonate is not self-inflammable as nanometer-sized powder. Also as a mixture with air (dust) under the influence of an ignition source, it is not inflammable, so there is no possibility of a dust explosion.
