FeGe2
metal· FeGe2
FeGe2 is an intermetallic compound combining iron and germanium in a 1:2 stoichiometric ratio, belonging to the class of transition metal germanides. This material exhibits metallic bonding characteristics and is primarily investigated in research contexts for its potential in thermoelectric and semiconducting applications, where the interplay between metallic and semiconducting properties can be engineered. FeGe2 and related iron germanides are of interest in advanced materials research for high-temperature structural applications and functional devices, though industrial adoption remains limited compared to conventional alloys.
