· Sb12 Ir4

Sb₁₂Ir₄ is an intermetallic compound combining antimony and iridium, belonging to the family of rare-earth-free metallic semiconductors with potential for high-temperature applications. This material is primarily of research interest rather than established industrial production, explored for its electronic properties and structural stability in extreme environments. The iridium content provides exceptional corrosion resistance and thermal stability, making it a candidate for advanced thermoelectric devices, high-temperature sensors, and specialized electronic components where conventional semiconductors reach their operational limits.
