Hf9AsW4
metal· JVASP-62389· Hf9AsW4
Hf9AsW4 is a hafnium-arsenic-tungsten intermetallic compound, likely belonging to the family of refractory metal phases studied for high-temperature structural applications. This is primarily a research material rather than a commercial alloy, with potential value in extreme-environment engineering where the combined refractory properties of hafnium and tungsten could provide thermal stability and wear resistance. The arsenic-containing chemistry suggests this compound may be under investigation for specialized applications requiring phase stability at elevated temperatures or in chemically aggressive environments.
