Description and Uses

Nickel chloride, NiCl2, is a water-soluble salt used in a variety of industries. It is typically produced and used either as an anhydrous salt or as a hydrate: nickel chloride hexahydrate as well as nickel chloride dihydrate. Nickel chloride is very rarely found in nature, and is produced via extraction from nickelcontaining ores via treatment with hydrochloric acid.

Nickel chloride is used for nickel plating cast zinc, as an agent in electrolytic refining of nickel, as a chemical intermediate for nickel catalysts and complex nickel salts, as an absorber of ammonia gas in industrial gas masks, as a catalyst in diarylamine and silicon tetrachloride production, as an agent in electrodeless plating of nickel, as an agent in tin–nickel alloy plating, and as a fungicide for control of rust and rustlike disease. However, workers exposed to different forms of nickel have an elevated risk of lung cancer. Besides, Ni and its compounds (particularly insoluble compounds of nickel) have been reported to be potent carcinogens and toxic agents in humans and experimental animals. Therefore, Ni compounds are considered to be an industrial/occupational health hazard.
