· JVASP-19803· YbAu2

YbAu₂ is an intermetallic compound formed from ytterbium and gold, belonging to the rare-earth metal family of advanced materials. This material is primarily of research and specialized industrial interest rather than mainstream engineering use, with applications leveraging its unique electronic and thermal properties in the contexts where ytterbium's f-electron behavior combines with gold's chemical stability. YbAu₂ and related rare-earth gold intermetallics are explored for thermoelectric devices, superconducting systems, and high-performance electronic applications where tuned electronic structure offers advantages over 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.
