· HoNiSb

HoNiSb is a ternary intermetallic compound composed of holmium, nickel, and antimony, representing a rare-earth transition metal system. This material belongs to the family of exotic intermetallics and is primarily of research interest rather than established in high-volume industrial production. The compound is investigated for potential applications in thermoelectric devices, magnetic materials, and advanced functional applications where rare-earth elements provide unique electronic or magnetic properties unavailable in conventional alloys.
