Nickel(II) sulfate

Product Name: Nickel(II) Sulfate

Chemical Formula: NiSO₄ · 6H₂O (Hexahydrate) / NiSO₄ (Anhydrous)

Key Features: Green crystalline powder or granules, high water solubility, stable in air, excellent nickel ion source.

Main Applications by Industry:

Electroplating Industry: As primary nickel source for electroplating and electroless nickel plating, providing corrosion-resistant and decorative nickel coatings on metals and plastics.

Battery Manufacturing: Key raw material for nickel-cadmium (Ni-Cd) and nickel-metal hydride (Ni-MH) rechargeable batteries, as well as nickel-rich cathode precursors for lithium-ion batteries.

Catalyst Production: Used in manufacturing nickel-based catalysts for hydrogenation reactions in petrochemical and edible oil processing industries.

Textile Dyeing: As mordant in textile dyeing processes to improve color fastness on fabrics.

Printing & Pigments: Raw material for producing nickel-based pigments and inks, as well as in surface treatment of printing rollers.

Ceramics & Glass: Used to impart green or yellow-green colors to ceramic glazes, glass, and enamels.

Electronics Industry: For producing nickel coatings on electronic components and circuit boards to enhance conductivity and solderability.

Metal Surface Treatment: As component in blackening solutions and other metal finishing applications.

Chemical Synthesis: As precursor for producing other nickel compounds, including nickel hydroxide, nickel carbonate, and nickel oxide.

Agriculture (Trace Element): As micronutrient source for nickel, recently recognized as essential trace element for certain crops (e.g., legumes, pecans) involved in urease enzyme function.

Handling & Safety:
May cause skin and eye irritation. Harmful if swallowed or inhaled. May cause allergic skin reaction. Use PPE (gloves, goggles, dust mask). Avoid dust formation. Store in sealed containers away from incompatible materials.
