· JVASP-66407· Ba4FeSi

Ba₄FeSi is an intermetallic compound containing barium, iron, and silicon—a rare-earth-adjacent metallic phase that belongs to the family of complex intermetallic structures. This material is primarily of research and materials science interest rather than established industrial production; it is studied for its structural properties and potential applications in high-temperature or specialized magnetic/electronic contexts where the barium-iron-silicon phase relationships offer unique properties unavailable in conventional alloys.

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.
