  • Applications

    Nickel Chloride (CAS 7718-54-9) is widely used as a source of Ni2+ in metal finishing and surface engineering, particularly in commercial nickel electroplating baths to produce decorative and corrosion-resistant coatings on steel, nonferrous metals, and plastics. It also serves as a key component in electroless nickel plating baths, where nickel ions are reduced to deposit nickel-containing coatings such as Ni-P alloys. Nickel Chloride is a common precursor in organonickel catalysis and related catalyst systems for transformations including hydrogenation, cross-coupling, and polymerization. It also serves as a nickel source for pigments and ceramic materials, where calcination or processing yields nickel oxide pigments and Ni-containing ceramic components. Additionally, it functions as a Ni2+ source in analytical chemistry and laboratory synthesis, for example as a reagent to prepare nickel complexes for analytical and coordination chemistry applications.
