Product Application of Nickel Sulfate (CAS No. 7786-81-4)

Nickel Sulfate exists in different hydrated forms, appearing as greenish-yellow, blue, or green crystals depending on the degree of hydration. It is widely used in nickel electroplating for coating iron and copper surfaces, providing uniform and durable metal finishes.

In addition, Nickel Sulfate is applied as a catalyst in chemical reactions and as a mordant in the textile industry to improve dye fixation and color fastness. It is also used as a coating material for specific industrial components, supporting surface treatment and corrosion-resistant applications.
