Description

Nickel Sulfate is a vital inorganic salt widely recognized for its role as a primary source of nickel ions in industrial and manufacturing processes. Its high solubility and consistent reactivity make it an essential precursor for electroplating and catalyst production. This compound is a key raw material for manufacturers in the surface finishing, battery, and chemical synthesis industries seeking reliable and high-purity nickel sources.

Application

• Electroplating & Surface Finishing: The primary application is as an electrolyte for nickel electroplating and electroless nickel plating, providing corrosion resistance, wear resistance, and a decorative finish on metals.
• Battery Manufacturing: Serves as a crucial cathode material precursor in the production of nickel-cadmium (Ni-Cd) and nickel-metal hydride (Ni-MH) rechargeable batteries.
• Catalyst Production: Used in the synthesis of hydrogenation catalysts and other nickel-based catalysts for the chemical and petrochemical industries.
• Ceramics & Pigments: Acts as a colorant and flux in the manufacture of ceramics, glasses, and inorganic pigments, imparting green or brown hues.
• Agriculture: Employed as a micronutrient in specialized fertilizers to correct nickel deficiencies in certain crops.
• Chemical Synthesis: Functions as a starting material for producing other nickel compounds, such as nickel carbonate and nickel hydroxide.

Quality Control

Our Nickel Sulfate is manufactured under a stringent quality management system to ensure batch-to-batch consistency and high purity. Production adheres to relevant industry standards, and the product is subjected to comprehensive analytical testing. A Certificate of Analysis (COA) detailing purity, assay, and impurity levels is provided with each shipment to guarantee it meets your specific application requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture. Recommended storage temperature is 15-25°C.
