In industry Electroplating Nickel Plating process originally used as a rust-resistant coating of iron. In the development of Nickel Plating also serves as a decorative coating of some other metals such as Aluminium, Zinc, or Stainlessteell Therefore we want to offer three types of nickel: Nickel Square, Nickel and Nickel Chloride Sulphate at fairly competitive prices.
Nickel chloride is the chemical compound NiCl2. The anhydrous salt is yellow, but the more familiar hydrate NiCl2 · 6H2O is green. In general nickel (II) chloride, in various forms, is the most important source of nickel for chemical synthesis. The nickel chlorides are deliquescent, absorbing moisture from the air to form a solution. Nickel salts are carcinogenic.
NiCl2 adopts the CdCl2 structure. In this motif, each Ni 2+ center is coordinated to six Cl- centers, and each chloride is bonded to three Ni (II) centers. In NiCl2 the Ni-Cl bonds have "ionic character". Yellow and black NiI2 adopt NiBr2 Similar structures, but with a different packing of the halides, Adopting the CdI2 motif.
In contrast, NiCl2 · 6H2O consists of separated trans- [NiCl2 (H2O) molecules more weakly linked to adjacent water molecules. Only four of the six water molecules in the formula are bound to the nickel, and the remaining two are water of crystallisation. Cobalt (II) chloride hexahydrate has a Similar structure. The hexahydrate Occurs in nature as the very rare mineral nickelbischofite.
The dihydrate NiCl2 · 2H2O adopts a structure intermediate between the hexahydrate and the anhydrous forms. It consists of infinite chains of NiCl2, wherein both centers are bridging chloride ligands. The trans octahedral centers on the sites occupied by aquo ligands. A tetrahydrate NiCl2 · 4H2O IS ALSO known.
