Er3Sb4Au3

Er₃Sb₄Au₃ is an intermetallic compound combining erbium (a rare-earth element), antimony, and gold. This material is primarily of research interest rather than established industrial production, belonging to the family of rare-earth intermetallics that are studied for potential electronic, magnetic, or thermoelectric applications. The specific combination of these elements suggests potential utility in specialized high-performance or extreme-environment applications where rare-earth properties are leveraged, though commercial adoption remains limited and engineering use would typically be confined to experimental or laboratory settings.
