Uses
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 diary amine 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 rust like disease. However, workers exposed to different forms of nickel have an elevated risk of lung cancer. Besides, Ni and its compounds 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.
