Ho1 Hf1 Os2
semiconductor· Ho1 Hf1 Os2
Ho₁Hf₁Os₂ is an experimental intermetallic compound combining holmium, hafnium, and osmium—a rare-earth/refractory metal system that belongs to the family of high-entropy or complex intermetallics under research for extreme-environment applications. This ternary phase is not yet established in commercial production, but compounds in this material family are investigated for their potential thermal stability, hardness, and oxidation resistance at elevated temperatures, making them relevant to aerospace and high-temperature structural research communities.
