NiS
metal· NiS
Nickel sulfide (NiS) is an intermetallic compound combining nickel and sulfur, typically appearing as a metallic solid with moderate stiffness and relatively high density. It is encountered primarily in pyrometallurgical nickel production as an intermediate phase during ore smelting and refining, and in laboratory research into transition metal sulfides. While not widely used as an engineered structural material in consumer or industrial applications, NiS is notable in the nickel industry as a processing intermediate and in materials science for studying metal-sulfide interfaces, catalytic properties, and corrosion behavior in sulfidic environments.

Export Control
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.
