CHEMICAL STRUCTURE AND DESCRIPTION:
Nickel Sulfamate (Ni(SO₃NH₂)₂·4H₂O) is the sulfamate salt of nickel in the +2 oxidation state. It consists of a nickel ion (Ni²⁺) and two sulfamate ions (SO₃NH₂⁻). It is hygroscopic and highly soluble in water. Commercially, it is typically supplied as a 50-60% aqueous solution. It is used in the electroplating industry for high-quality nickel plating baths, in electronic and precision engineering applications. Nickel sulfamate baths produce low-stress, soft, and ductile nickel deposits compared to nickel chloride baths.

SUMMARY:
Nickel Sulfamate (Ni(SO₃NH₂)₂·4H₂O, CAS 13770-89-3) is a clear green liquid or green crystalline solid. It is highly soluble in water and hygroscopic. Commercially, it is typically supplied as a 50-60% aqueous solution.
Its most important applications include use in electroplating (high-quality nickel plating baths), in electronic and precision engineering applications, and in metal surface treatment.
Nickel Sulfamate baths produce low-stress, soft, and ductile nickel deposits compared to nickel chloride baths. They offer high plating speed and excellent throwing power.
Nickel compounds may cause allergic reactions and long-term cancer risk. Harmful if swallowed or inhaled. Causes skin irritation, allergic skin reactions, and respiratory tract irritation. Very toxic to aquatic life. Storage should be in cool, dry, well-ventilated areas, in tightly closed containers, away from strong oxidizers and acids.
