· JVASP-63402· Ho3Sb4Au3

Ho3Sb4Au3 is an intermetallic compound combining holmium (rare earth), antimony, and gold—a ternary metal system that has been primarily investigated in materials research rather than established in widespread industrial production. This compound belongs to the family of rare-earth-based intermetallics, which are of interest for fundamental studies of crystal structure, electronic properties, and magnetic behavior. While not a conventional engineering material with broad commercial use, compounds in this chemical family are explored for potential applications in thermoelectrics, magnetism research, and high-performance functional materials where the combination of rare-earth and noble-metal elements may offer unique electronic or thermal properties.
