NaFe4Sb12
metal· JVASP-23337· NaFe4Sb12
NaFe4Sb12 is an intermetallic compound belonging to the skutterudite family, characterized by a cage-like crystal structure with sodium and iron atoms surrounding antimony. This material is primarily investigated in thermoelectric research for its potential to convert thermal gradients into electrical energy, with particular interest in high-temperature power generation and waste heat recovery applications where its phonon-scattering cage structure can reduce thermal conductivity while maintaining electrical conductivity.
