· JVASP-15128· CeFe2Si2

CeFe₂Si₂ is an intermetallic compound combining cerium, iron, and silicon in a defined stoichiometric ratio, belonging to the class of rare-earth iron silicides. This material is primarily of research interest rather than widespread industrial production, investigated for its potential in high-temperature structural applications, magnetic device components, and thermoelectric systems where the rare-earth element provides unique electronic and thermal properties that differ significantly from conventional iron-silicon alloys.
