Nickel sulfide - Wikipedia

Nickel sulfide is an inorganic compound with the formula NiS. It is a black solid that is produced by treating nickel(II) salts with hydrogen sulfide.Many nickel sulfides are known, including the mineral millerite, which also has the formula NiS.Aside from being useful ores, nickel sulfides are the products of desulfurization reactions, and are sometimes used as catalysts.
