· JVASP-14272· YbAu4

YbAu₄ is an intermetallic compound composed of ytterbium and gold, belonging to the class of rare-earth metal intermetallics. This material is primarily studied in condensed matter physics and materials research rather than as an established engineering alloy, with potential applications in low-temperature physics, Kondo systems research, and specialized electronic devices where rare-earth-gold compounds exhibit unusual electronic and magnetic properties.

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.
