1. Basic Information
Name: Nickel sulfamate
Alias: Nickel(II) sulfamate tetrahydrate
CAS No.: 13770-89-3
Molecular Formula: Ni1S2N2O6·H8O4
Molecular Weight: 322.89
2. Physical and Chemical Properties
Physical Properties
- Appearance: Green transparent crystalline powder
- Odor: Odorless
- Solubility: Highly soluble in water; slightly soluble in ethanol; insoluble in ketones, aromatic hydrocarbons
- Hygroscopicity: Moderately hygroscopic, easy to absorb moisture in humid air
- Aqueous solution: Weakly acidic green solution, low internal stress electroplating solution raw material
Chemical Properties
- Molecular Structure: Ionic hydrate composed of Ni1 cation and two sulfamate anions, with four crystal water molecules
- Thermal stability: Loses crystal water gradually when heated above 100 °C; decomposes above 220 °C to release sulfur-containing irritant gas
- Precipitation reaction: Reacts with strong alkali to generate nickel hydroxide green precipitate
- Electrochemical characteristic: Low sulfate impurity, suitable for high-speed nickel plating, no brittle coating
- Photostability: Stable under indoor light, no discoloration
- Compatibility: Compatible with electroplating additives, weak acid systems; incompatible with strong alkalis, sulfide salts, heavy metal precipitants

Safety Warning
Toxic nickel compound, allergenic. Dust severely irritates skin, eyes and respiratory tract; long-term contact easily causes nickel contact dermatitis, inhalation has potential carcinogenic risk. Wear dust mask, acid-resistant gloves and full-face protective goggles during all operations. Strictly avoid mixing with sulfides to generate toxic nickel sulfide precipitate. Waste liquid requires heavy metal precipitation treatment before discharge; solid residues are hazardous heavy metal waste and must be professionally recycled.
