In this study, we investigate the microstructure of InSb particles to which several elements are added (Ag, Sn, Al, and Fe). The microstructure of these particles changes depending on the kind of element incorporated. InSb becomes the primary phase and exhibits a polycrystalline structure by adding Ag or Sn, whereas it becomes a secondary phase by adding Al or Fe. When Al is added, AlSb becomes the primary phase and the InSb phase is solidified as fine crystal grains. When Fe is added, FeSb becomes the primary phase and InSb phase is solidified as large crystal grains. We consider that the AlSb phase becomes a nucleation site; however, the FeSb phase does not become a nucleation site of the secondary phase of the InSb compound. In addition, we suggest that addition of Fe is effective for monocrystallization of InSb particles.
