Physical Properties and Applications of Nickel Sulfate

Nickel sulfate is a widely used nickel salt in the electroplating and electroless plating industries. It serves as the primary source of nickel ions in these processes, allowing the release of Ni²⁺ and SO₄²⁻ ions essential for metal deposition.

Nickel sulfate solution has a relatively low boiling point elevation and its solubility changes significantly with temperature, making it suitable for evaporation and crystallization processes. To obtain nickel sulfate hexahydrate (NiSO₄·6H₂O), the solution is first concentrated through either multi-effect evaporation or MVR evaporation, depending on energy cost and scale. The concentrated liquid is then cooled to form crystals, using either a batch crystallizer or a continuous system, depending on production needs.

    2. MVR Evaporator
      Evaporation capacity 500kg/h-60t/h
      Evaporation temperature 40-100℃
      The MVR evaporator is an advanced energy-efficient evaporation system that recycles its own secondary steam to reduce reliance on external energy sources. It compresses and reuses vapor generated during evaporation, making full use of latent heat from secondary steam and condensate within the evaporation system. View Details
