Sm2Fe15Si2
metal· JVASP-143136· Sm2Fe15Si2
Sm₂Fe₁₅Si₂ is an intermetallic compound belonging to the rare-earth iron silicide family, combining samarium (a rare-earth element) with iron and silicon to form a hard, brittle metallic phase. This material is primarily investigated in research contexts for permanent magnet applications and high-temperature structural components, where its rare-earth iron base offers potential for enhanced magnetic properties or thermal stability compared to conventional iron alloys. Its use remains largely experimental and specialized, directed toward advanced magnetic device engineering and materials science exploration rather than commodity industrial production.
