Antimony iodide (SbI3), also known as antimony triiodide or antimony(III) iodide, appears as ruby-red solid crystals in its pure state. Produced via the reaction of antimony with iodine or antimony trioxide with hydroiodic acid, antimony triiodide is notable for its unique structure among antimony iodides and the variation in its structure across different phases. 


While antimony iodide currently has a limited number of practical applications, it remains of interest to commercial and academic researchers for its potential in a number of additional fields. Current applications and potential applications include:

  • Thermo-electrical materials. The primary commercial and academic use of antimony iodide is currently its use in the manufacturing of certain thermos-electrical materials.
  • Doping. Antimony iodide has value as a doping agent for a number of applications. Most notably, it’s used in the doping of thermos-electrical materials, but it has potential in the production of other specialty materials.
  • Nanoparticle research. Like many iodine compounds, antimony iodide has significant value in nanoparticle research, with special attention on its formation and on its potentially valuable optical properties.
