· JVASP-15089· YbFe2Si2

YbFe2Si2 is an intermetallic compound belonging to the rare-earth iron silicide family, combining ytterbium with iron and silicon in a defined stoichiometric ratio. This material is primarily of research interest rather than established industrial production, studied for its potential in magnetism, thermal transport, and electronic applications owing to the magnetic properties contributed by ytterbium and the structural stability of the Laves-phase-related crystal structure. Engineers and materials researchers evaluate this compound for niche applications in magnetic devices, thermoelectric systems, and high-performance alloys where rare-earth strengthening and unusual electronic behavior are advantageous.

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.
