· JVASP-128313· Yb3Au

Yb₃Au is an intermetallic compound in the rare-earth–gold system, belonging to a class of materials that combine ytterbium (a lanthanide) with gold. This compound is primarily of research and developmental interest rather than established in high-volume industrial use; it represents the broader family of rare-earth intermetallics being investigated for specialized electronic, magnetic, and structural applications where conventional alloys fall short.

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.
