· 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.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
