nickel applications

...Nickel is primarily sold for first use as refined metal (cathode, powder, briquet, etc.) or ferronickel. About 65% of the nickel consumed in the Western World is used to make austenitic stainless steel. Another 12% goes into superalloys (e.g., Inconel 600) or nonferrous alloys (e.g., cupronickel). Both families of alloys are widely used because of their corrosion resistance. The aerospace industry is a leading consumer of nickel-base superalloys. Turbine blades, discs and other critical parts of jet engines are fabricated from superalloys. Nickel-base superalloys are also used in land-based combustion turbines, such those found at electric power generation stations. The remaining 23% of consumption is divided between alloy steels,
rechargeable batteries, catalysts and other chemicals, coinage, foundry products, and plating. The principal commercial chemicals are the carbonate (NiCO3), chloride (NiCl2), divalent oxide (NiO), and sulfate (NiSO4). In aqueous solution, the divalent nickel ion has an emerald-green color....
