W&Q's nickel chloride hexahydrate is an inorganic salt with the chemical formula NiCl₂·6H₂O (CAS No.: 7791-20-0) . It is a primary source of nickel ions (Ni⊃2;⁺) and typically appears as green crystalline powder or granular crystals . It is highly soluble in water and ethanol, and its aqueous solutions are slightly acidic with a pH range of 4.0-6.0 (50g/L, 25℃) .
1.Physical & Handling (vs. Anhydrous Form):
Moderate Hygroscopicity & Stability: The hexahydrate form has mild moisture absorption and remains stable under sealed conditions. Unlike anhydrous nickel chloride, which easily absorbs moisture and cakes, it maintains free-flowing properties during storage and use .
Uniform Crystalline Structure: Produced as consistent, free-flowing crystals, ensuring easy weighing, accurate dosing, and convenient operation in industrial and laboratory settings .
Controlled Solubility: Rapidly dissolves in both cold and hot water with a predictable solubility profile, ideal for preparing electroplating baths, disinfectant solutions, and ammonia absorption agents .
2.Functional & Performance:
High-Purity Nickel Source: Completely dissociates in aqueous solutions to release Ni⊃2;⁺, the active form for electroplating, disinfection, and complexation reactions .
Environmental & Safety Advantages (vs. Traditional Agents): It is a low-toxicity alternative to cyanide-containing electroplating agents and formaldehyde-based disinfectants , helping industries comply with environmental regulations .
3.Economic & Practical:
Cost-Effective Production: Manufactured by two mature processes (metal nickel acidolysis or nickel waste recycling) , which are straightforward and scalable for mass production .
Long Shelf Life: Properly sealed and stored in cool dry conditions, it maintains stable quality for over 36 months without degradation .
Disinfection: Diluted solutions are used for industrial circulating water disinfection and equipment surface sterilization, effectively inhibiting the growth of harmful microorganisms .
Ammonia Absorbent: Applied in industrial waste gas treatment and gas masks to absorb ammonia, preventing air pollution and ensuring workplace safety .
Catalysis & Chemical Manufacturing: Key raw material for preparing nickel-based catalysts, dry batteries, and invisible ink .
Metal Processing: Added in aluminum alloy chemical polishing to enhance surface smoothness and polishing quality .
Laboratory & Analytical Chemistry: Used as a reagent for complexometric titration and qualitative analysis of metal ions .
Environment: Store in a cool, dry warehouse with relative humidity 40%-60% and temperature 15-25℃; avoid direct sunlight and high humidity .
Packaging: Keep sealed in original containers to prevent moisture absorption and contamination .
Separation: Store separately from strong acids, alkalis, and oxidizing agents to avoid chemical reactions .
How to treat wastewater containing nickel chloride?
Chemical Precipitation: Adjust pH to 10-12 with alkaline agents (e.g., NaOH) to form nickel hydroxide precipitates; add Fenton reagent to break down complexes if needed .
Ion Exchange: Use cation exchange resins to adsorb Ni⊃2;⁺, which can be regenerated and recycled for plating baths .
What is the difference between nickel chloride hexahydrate and nickel sulfate hexahydrate in electroplating?
Nickel Chloride: Provides Cl⁻ ions that promote anode dissolution and improve coating adhesion; suitable for decorative and functional plating of complex workpieces .
Nickel Sulfate: Higher nickel content but no Cl⁻; mainly used for high-gloss decorative plating .
Selection Tip: Nickel chloride is preferred for corrosion-resistant coatings and parts requiring strong adhesion.
What key indicators should be checked on the Certificate of Analysis (CoA)?
Nickel Content: ≥23.7% (electroplating grade) .
Heavy Metal Impurities: Limits for Fe (≤0.001%), Cu (≤0.001%), Pb (≤0.001%), Cd (≤0.001%) (critical for electroplating and high-purity applications) .
Water Insoluble Matter: ≤0.04% (electroplating grade), ≤0.005% (reagent grade) .
pH Value: 4.0-6.0 (50g/L solution) .
