Ta4Cu3Ni9
metal· JVASP-121579· Ta4Cu3Ni9
Ta4Cu3Ni9 is a quaternary intermetallic compound combining tantalum, copper, and nickel—a research-phase material rather than an established commercial alloy. This composition lies in the tantalum-copper-nickel phase space and represents exploratory work into high-density metallic compounds, likely investigated for their thermal stability, electronic properties, or potential use in specialized high-performance applications where the unique phase chemistry offers advantages over conventional binary or ternary alloys.
