Tb2Fe4Si9
metal· JVASP-148232· Tb2Fe4Si9
Tb2Fe4Si9 is an intermetallic compound combining terbium (a rare-earth element), iron, and silicon. This material belongs to the rare-earth iron silicide family, primarily of interest in materials research rather than established industrial production. The compound is investigated for potential applications in magnetic materials and high-temperature structural applications where the rare-earth contribution may enhance magnetic properties or thermal stability, though it remains in the research phase without widespread commercial deployment.
