Ta2NiS5
metal· JVASP-12093· Ta2NiS5
Ta2NiS5 is an intermetallic compound combining tantalum, nickel, and sulfur, representing a quaternary transition-metal sulfide phase. This is a research-stage material rather than an established industrial grade; compounds in this family are investigated for their potential in catalysis, energy storage, and high-temperature applications where the combination of refractory (tantalum) and catalytically active (nickel) elements offers theoretical advantages over single-metal alternatives.
