Hf1 Ga1 Ir2
semiconductor· Hf1 Ga1 Ir2
HfGaIr₂ is an intermetallic compound combining hafnium, gallium, and iridium in a 1:1:2 stoichiometric ratio. This is a research-phase material belonging to the high-entropy or complex intermetallic family, with potential applications in extreme-temperature and high-performance structural contexts where conventional superalloys reach their limits. The material's appeal lies in its density and melting point characteristics typical of refractory intermetallics, making it relevant for aerospace propulsion and thermal barrier applications where weight and thermal stability are critical trade-offs.
