· JVASP-49151· Y3Sb4Au3

Y3Sb4Au3 is an intermetallic compound combining yttrium, antimony, and gold, representing a rare-earth metal system with potential applications in advanced functional materials. This is primarily a research-phase material rather than an established industrial compound; intermetallics of this type are studied for their unique electronic, magnetic, or thermoelectric properties that differ fundamentally from conventional alloys. Engineers would consider materials in this family when conventional metallic solutions cannot meet requirements for extreme environments, electronic devices, or applications demanding properties that emerge only from specific atomic ordering.
