1. Electroplating industry: Nickel sulfate is an important raw material for electroplating nickel and chemical nickel plating. During the electroplating process, it can provide nickel ions for the plated parts, so that a uniform and dense nickel plating layer is formed on the surface of the plated parts, which plays a protective and decorative role. It is widely used in electroplating processing of automotive parts, electronic equipment, hardware products, etc.
2. Battery industry: It is one of the key raw materials for the preparation of various batteries such as nickel-hydrogen batteries, nickel-cadmium batteries and lithium-ion batteries. In nickel-hydrogen batteries, nickel sulfate is used to prepare positive electrode materials, which has an important impact on the battery’s charge and discharge performance, cycle life, etc.
3. Catalyst field: Nickel sulfate can be used as a catalyst or catalyst carrier for various chemical reactions. For example, in some organic synthesis reactions, such as hydrogenation reactions and dehydrogenation reactions, nickel sulfate can change the rate of chemical reactions and improve the selectivity and conversion rate of reactions.
4. Chemical raw materials: It is an important intermediate for the preparation of other nickel compounds. By reacting with other chemical substances, various nickel compounds such as nickel oxide and nickel hydroxide can be prepared. These compounds are widely used in ceramics, glass, magnetic materials and other fields.
Printing and dyeing industry: Used as a mordant in the printing and dyeing industry, it helps the dye to adhere better to the fabric, improves the dyeing effect and color stability.
