In the electroplating industry nickel plating process was 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 aluminum, zinc, or stainlessteell therefore we want to offer three types of nickel is a nickel square, nickel chloride and nickel sulphate at a fairly competitive price.
Nickel sulfate, usually refers to an inorganic compound with the formula NiSO 4 (H2O) 6. blue highly soluble salt is a common source of Ni 2+ ions for electroplating.
About 40,000 tons produced in 2005. It is mainly used for electroplating nickel.
In 2005-06, nickel sulfate is a top allergens in the patch test (19.0%).
Salt is usually obtained as a byproduct of copper refining. It is also produced by dissolution of nickel metal or nickel oxides in sulfuric acid.
water solution of nickel sulfate reacts with sodium carbonate to precipitate nickel carbonate, nickel-based precursors for catalysts and pigments.  The addition of ammonium sulfate to an aqueous solution of nickel sulfate precipitate Ni (NH4) 2 (SO4) 2 · 6H2O. Solid blue is analogous to Mohr salt, Fe (NH4) 2 (SO4) 2 · 6H2O. 
Nickel sulfate is used in the laboratory. The column used in polyhistidine-tagging, useful in biochemistry and molecular biology, which is regenerated by nickel sulfate. aqueous solution of NiSO 4 · 6H2O and hydrate related to react with ammonia to give [Ni (NH3) 6] SO4 and with ethylenediamine to give [Ni (H2NCH2CH2NH2) 3] SO4. The latter is sometimes used as a calibrant for magnetic susceptibility measurements because it does not have a tendency to moisturize.
