Strontium does not have direct applications as a pure metal. However, its compounds can be commercially used, as it is case of the carbonate ((SrCO3)) and of the oxide (SrO), used in the sugar industry, or the strontium nitrate (Sr(NO3)2), used in pyrotechnics, fireworks preparation and signal or alarm fires, because it produces a bright red flame. Strontium sulfide is used in beauty treatments and in the production of luminescent paints due to its specific properties. The bromide and the iodide have applications in Medicine, although limited.
