ErFe2Si2
metal· JVASP-15624· ErFe2Si2
ErFe2Si2 is an intermetallic compound combining erbium (a rare-earth element), iron, and silicon in a defined stoichiometric ratio. This material belongs to the family of rare-earth iron silicides, which are primarily investigated for magnetic and thermal properties in research and specialized applications rather than commodity use. ErFe2Si2 is of particular interest in magnetism research, materials science studies of Kondo lattices and heavy fermion systems, and potentially in high-temperature or magnetic device applications where rare-earth intermetallics offer unique electronic behavior unavailable in conventional alloys.

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.
