ErAu2
metal· ErAu2
ErAu₂ is an intermetallic compound combining erbium (a rare earth element) with gold in a 1:2 atomic ratio. This material exists primarily in research and specialized contexts rather than broad industrial production, where it is studied for its potential in high-performance applications leveraging the unique electronic and thermal properties of rare earth–noble metal systems. ErAu₂ and related rare earth–gold intermetallics are of interest in thermoelectric devices, magnetic applications, and advanced materials research, where the combination of erbium's magnetic and electronic characteristics with gold's chemical stability and conductivity offers potential advantages over simpler alternatives.

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.
