· JVASP-112667· Lu2Fe4Si9

Lu2Fe4Si9 is an intermetallic compound combining lutetium, iron, and silicon—a rare-earth iron silicide belonging to the class of ternary intermetallics. This material is primarily of research interest rather than established industrial production, explored for its potential in magnetic applications, high-temperature performance, and materials physics studies due to the magnetic properties of iron combined with the thermal stability contributions of lutetium and silicon.

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.
