In2Bi

In₂Bi is an intermetallic ceramic compound composed of indium and bismuth, representing a rare-earth/post-transition metal system that exists primarily in academic and exploratory research contexts rather than established commercial use. This material belongs to the family of bismuth-based intermetallics, which are investigated for potential applications in thermoelectric devices, optoelectronics, and semiconductor research where phase stability and electronic properties at specific compositions are of interest. The In₂Bi system is notable for its potential to bridge conventional semiconductors and metallic conductors, though practical engineering adoption remains limited compared to more mature material systems.
