Ho1 Hf1 Ru2
semiconductor· Ho1 Hf1 Ru2
Ho1Hf1Ru2 is an intermetallic compound combining holmium, hafnium, and ruthenium in a 1:1:2 atomic ratio. This is a research-phase material within the rare-earth transition metal intermetallic family, explored primarily for high-temperature structural applications where conventional superalloys reach their limits. The combination of refractory elements (hafnium, ruthenium) with a rare-earth constituent (holmium) targets extreme-environment performance, though industrial deployment remains limited and material behavior is still being characterized.
