· JVASP-145103· Er3Fe4Ge4

Er₃Fe₄Ge₄ is an intermetallic compound combining erbium (a rare earth element), iron, and germanium in a fixed stoichiometric ratio. This material belongs to the family of rare-earth iron germanides, which are primarily of scientific and research interest rather than established commercial use. The compound is notable for its potential in magnetic and electronic applications due to the magnetic properties contributed by erbium and iron; such materials are investigated for specialized high-performance devices where conventional alloys are insufficient.

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.
