· Fe4 Sb12

Fe4Sb12 is an iron-antimony binary compound belonging to the skutterudite family of semiconductors, characterized by a cage-like crystal structure. This material is primarily investigated for thermoelectric applications where it can convert waste heat into electrical power, particularly in automotive exhaust recovery and industrial heat harvesting systems. Fe4Sb12 and related skutterudites are notable for their potential to achieve high thermoelectric performance through phonon scattering in the cage structure, making them candidates to replace traditional thermoelectric materials in mid-to-high temperature ranges.
