· CeFe2Co2Sb12

CeFe2Co2Sb12 is a rare-earth transition metal intermetallic compound belonging to the skutterudite family, characterized by a cage-like crystal structure containing cerium atoms. This is a research-phase material primarily investigated for thermoelectric applications, where the rattling behavior of rare-earth atoms in the skutterudite framework offers potential to reduce thermal conductivity while maintaining electrical conductivity. Materials in this family are being developed as alternatives to conventional thermoelectrics for waste heat recovery and power generation in moderately high-temperature regimes.
