HoNbOs2
metal· JVASP-39999· HoNbOs2
HoNbOs2 is an experimental intermetallic compound containing holmium, niobium, and oxygen, representing a rare-earth refractory metal oxide system. This research-phase material belongs to the family of high-density mixed-metal oxides being investigated for extreme-environment applications where conventional superalloys reach their limits. While not yet commercially established, compounds in this chemical family are studied for their potential in high-temperature structural applications, advanced catalysis, and materials requiring exceptional density combined with thermal stability.
