Product Description

Product Description

Basic Information

• Chemical Name: Nickel sulfamate / Nickel(II) sulfamate / Nickel diaminosulfonate
• Molecular Formula: Ni(NH2SO3)2·4H2O (tetrahydrate form, common commercial product)
• Molecular Weight: 250.86 g/mol (anhydrous); 322.93 g/mol (tetrahydrate)
• CAS Number: 13770-89-3 (anhydrous); 13770-89-3 (tetrahydrate)
• Appearance:
  • Anhydrous: Green crystalline powder.
  • Tetrahydrate: Green crystals with a metallic luster.
• Physical Properties:
  • Solubility: Highly soluble in water (146 g/100 mL at 20°C), liquid ammonia, and ethanol; slightly soluble in acetone.
  • Melting Point: Decomposes above 110°C (loses water of crystallization first, then forms basic salts).
  • pH: Aqueous solutions are acidic due to hydrolysis of sulfamate ions.
  • Hygroscopicity: Absorbs moisture in humid air; slowly effloresces in dry air.

Chemical Properties

• Stability: Stable under normal storage conditions but prone to hydrolysis at high temperatures or low pH.
• Reactivity:
  • Hydrolyzes in aqueous solutions to release NH3 and H2SO4, affecting plating bath pH.
  • Forms complex ions with amines or ammonia, enhancing solubility and plating performance.
  • Reacts with strong bases to precipitate nickel hydroxide.

Applications in Electroplating

1. Key Advantages as an Electroplating Bath Component:
   • Low Internal Stress: Deposits have minimal tensile/compressive stress, ideal for precision components.
   • High Plating Rate: Enables faster nickel deposition compared to traditional sulfate baths.
   • High Solubility: Allows high nickel ion concentrations, supporting high-current-density plating.
   • Environmental Friendliness: Reduces sulfuric acid usage (vs. sulfate baths), lowering waste treatment costs.
2. Industrial Applications:
   • Electronics: Low-stress nickel plating for PCBs, connectors, and semiconductor packaging (as a base for noble metals to enhance wear resistance).
   • Automotive & Aerospace: Wear-resistant coatings for engine parts, hydraulic components, and aerospace fasteners.
   • Electroforming: Production of precision molds, CD/DVD stamper plates, and micro-electromechanical systems (MEMS).
   • Decorative Plating: Underlayers for chromium plating in automotive trim and hardware.

Safety and Handling

• Toxicity:
  • Harmful if ingested or inhaled; may cause skin/eye irritation. Nickel compounds are classified as possible human carcinogens (IARC Group 2B).
• GHS Hazards:
  • H351 (Suspected of causing cancer), H315 (Causes skin irritation), H319 (Causes serious eye irritation).
• Handling Precautions:
  • Wear protective gloves, goggles, and a respirator in dusty environments.
  • Avoid contact with skin and eyes; rinse thoroughly with water in case of exposure.
• Storage:
  • Store in a cool, dry, ventilated area, sealed to prevent moisture absorption. Keep away from strong bases and oxidizing agents.
