A labeled periodic table entry for antimony shows its symbol Sb, atomic number 51, atomic weight 121.76, electron configuration, and name. It is a solid, weakly acidic other metal with a rhombohedral crystal structure at room temperature.
antimony Properties of antimony.

In semiconductor technology, highly purified antimony is used to prepare intermetallic compounds, specifically indium antimonide and gallium antimonide. These compounds are utilized in the production of diodes and infrared detectors.1

  • Indium antimonide (InSb): This synthetic compound is a semiconducting and photosensitive material, making it particularly valuable for use in infrared photodetectors.2
  • Gallium antimonide (GaSb): Along with other compounds formed by gallium and Group 15 elements, gallium antimonide possesses valuable semiconductor and optoelectronic properties.3
