· JVASP-18613· LuInAu2

LuInAu₂ is an intermetallic compound composed of lutetium, indium, and gold, belonging to the family of rare-earth-containing metallic compounds. This material is primarily of research and scientific interest rather than established in high-volume industrial production, with potential applications in specialized fields requiring unique combinations of density, stiffness, and metallic properties. The incorporation of lutetium (a rare earth element) and the precise stoichiometry suggest possible use in advanced functional materials, though widespread engineering adoption remains limited pending further development and cost optimization.
