· JVASP-15101· HoSi2Ni2

HoSi2Ni2 is a ternary intermetallic compound combining holmium, silicon, and nickel, belonging to the rare-earth metal silicide family. This material is primarily of research interest for high-temperature structural applications and advanced functional devices, where the combination of rare-earth elements with transition metals offers potential for enhanced mechanical properties, thermal stability, or magnetic characteristics. Engineers would consider this material in specialized aerospace, energy, or electronics contexts where conventional superalloys or silicides are insufficient, though industrial adoption remains limited and material availability is constrained.
