Nickel Sulfate for Sale

Nickel sulfate usually refers to the inorganic compound with the formula NiSO4(H2O)6. It is also called Nickelous sulfate, 6-hydrate; Sulfuric Acid, Nickel (2+) Salt, Hexahydrate; Nickel Monosulfate Hexahydrate; Blue Salt; Single Nickel Salt; Nickelsulfat (German). This highly soluble blue-coloured salt is a common source of the Ni2+ ion for electroplating. Nickel sulfate is paramagnetic. At least seven sulfate salts of nickel(II) are known. It is mainly used in lectroplating, Organic chemical synthesis, Metal colouring, Dye mordant, Manufacturing other nickel salts, Ni-Cd battery. Also used in the manufacture of nickel catalysts and nickel salt as raw material. Containing 6 molecules of water of crystallization of the alpha type nickel sulfate as blue and green square crystal, at 533 degrees C into beta type green transparent crystal.

These salts differ, sometimes subtly, in terms of their hydration or structural details. Nickel is a hard, malleable, ductile, lustrous, silvery white, ferromagnetic metallic element in Group VIII of periodic table; atomic number 28; atomic mass 58.69; melting point ca 1,453°C; boiling point ca  2,732°C; specific gravity 8.902 g/cm3; valence 0, 1, 2, 3; electronic config. 2-1 or 4s 23ds8. The common tetragonal hexahydrate crystallizes from aqueous solution between 30.7 and 53.8 °C. Below these temperatures, a heptahydrate crystallises and above these temperatures an orthorhombic hexahydrate forms. The yellow anhydrous form, NiSO4, is a high melting solid. Nickel is combined with many other elements, including chlorine, sulfur, and oxygen, exist. This material produced by heating the hydrates above 330 °C.  It decomposes at still higher temperatures to nickel oxide.

Nickel sulfate is usually obtained as a by-product of copper refining. It is also produced by dissolution of nickel metal or nickel oxides in sulfuric acid. Nickel dissolves in dilute acids slowly but will be passive with nitric acid like iron. Approximately 40,000 tonnes were produced in 2005. It is mainly used for electroplating of nickel.
