· 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.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
