Er1 Ta1 Ru2

Er₁Ta₁Ru₂ is an intermetallic compound combining erbium, tantalum, and ruthenium in a 1:1:2 atomic ratio. This is a research-phase material within the high-entropy and refractory intermetallic family, typically studied for extreme-temperature structural applications where conventional superalloys reach their limits. The combination of refractory metals (Ta, Ru) with rare-earth erbium suggests investigation into oxidation resistance, creep strength, and thermal stability at elevated temperatures—making it of potential interest for aerospace propulsion, nuclear systems, or power generation where materials must survive prolonged exposure above 1200°C.
