· Y(FeSi)2

Y(FeSi)₂ is an intermetallic compound combining yttrium with iron and silicon, belonging to the class of rare-earth-transition metal silicides. This material is primarily of research and development interest rather than established industrial production, being studied for potential applications in high-temperature structural materials and thermoelectric devices where the combination of metallic bonding and intermetallic ordering can provide enhanced stiffness and thermal properties.

Export Control

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.
