The Uses of Nickel bis(sulphamidate)

Nickel sulfamate is used as an electrolyte in nickel electroplating systems.

The Uses of Nickel bis(sulphamidate)

Nickel plating Nickel(II) sulfamate is used for electroplating and as a surface treating agent. It finds application in metal coloring and casting.

Preparation

Nickel sulfamate is prepared by heating an aqueous solution of sulfamic acid, H₂NSO₃H, with fine nickel powder or black nickel oxide under controlled conditions:2H₂NSO₃H + NiO → Ni(SO₃NH₂)₂ + H₂O
At ordinary temperatures, sulfamic acid hydrolyzes slowly forming ammonium bisulfite. However, when heated it hydrolyzes rapidly forming sulfuric acid. Therefore nickel sulfamate should be prepared rapidly before any sulfamic acid hydrolysis occurs due to longer contact time with water.
Nickel sulfamate also can be prepared by the action of sodium sulfamate on nickel carbonate: 2H₂NSO₃Na + NiCO₃ → Ni(SO₃NH₂)₂ + Na₂CO₃
Nickel sulfamate is usually not isolated from its product mixtures. The product solution is sold for commercial applications.

Flammability and Explosibility

Non flammable

Safety Profile

Confirmed human carcinogen. Poison by intraperitoneal route. When heated to decomposition it emits very toxic fumes of SOx and NOx. See also NICKEL COMPOUNDS.
