Nickel is a silvery transition metal of group 10, valued for corrosion resistance, strength at high temperature, and its ability to form useful alloys. It is ferromagnetic near room temperature and commonly occurs in the +2 oxidation state, although several other states are known in coordination chemistry. Natural nickel is mostly found in sulfide and laterite ores, and it is a key metal for stainless steels, superalloys, plating, catalysts, and rechargeable batteries.
Nickel is silvery white and takes on a high polish. It is hard, malleable, ductile, somewhat ferromagnetic, and a fair conductor of heat and electricity. It belongs to the iron-cobalt group of metals and is chiefly valuable for the alloys it forms.
The name derives from the German Nickel for "deceptive little spirit" because miners called mineral niccolite (NiAs) by the name Kupfernickel (false copper) because it resembled copper ores in appearance, but no copper was found in the ore. It was discovered by the Swedish metallurgist Axel-Frederik Cronstedt in 1751.
Nickel was discovered by the Swedish chemist Axel Fredrik Cronstedt in the mineral niccolite (NiAs) in 1751. Today, most nickel is obtained from the mineral pentlandite (NiS·2FeS). Most of the world's supply of nickel is mined in the Sudbury region of Ontario, Canada. It is believed that this large deposit of nickel ore is a result of an ancient meteor impact.
From the German word Nickel (Satan), and from kupfernickel, Old Nick's copper. Cronstedt discovered nickel in 1751 in kupfernickel (niccolite).
Pure nickel is a lustrous, silvery-white metal with a faint golden tinge. It is hard, ductile, and malleable, and it can take a high polish. Compact nickel resists attack by air and water under ordinary conditions because a thin protective surface film forms.
The largest use of nickel is in alloys, especially stainless steels, where it improves toughness, corrosion resistance, and formability. Nickel-base superalloys are used in turbine blades and other high-temperature parts. The metal is also used for electroplating, coinage alloys, catalysts such as Raney nickel, and electrical contacts. Nickel compounds and nickel metal are important in batteries, including nickel-cadmium, nickel-metal hydride, and many lithium-ion cathode chemistries.
Nickel is a hard, corrosion resistant metal. It can be electroplated onto other metals to form a protective coating. Finely divided nickel is used as a catalyst for the hydrogenation of vegetable oils. Adding nickel to glass gives it a green color. A single kilogram of nickel can be drawn into 300 kilometers of wire. Nickel is also used to manufacture some types of coins and batteries.
Nickel is alloyed with other metals to improve their strength and resistance to corrosion. Nickel is alloyed with steel to make armor plate, vaults and machine parts. It is alloyed with copper to make pipes that are used in desalination plants. Very powerful permanent magnets, known as Alnico magnets, can be made from an alloy of aluminum, nickel, cobalt and iron.
It is extensively used for making stainless steel and other corrosion-resistant alloys such as Invar(R), Monel(R), Inconel(R), and the Hastelloys(R). Tubing made of copper-nickel alloy is extensively used in making desalination plants for converting sea water into fresh water.
Nickel, used extensively to make coins and nickel steel for armor plates and burglar-proof vaults, and is also a component in Nichrome(R), Permalloy(R), and constantan.
Nickel gives glass a greenish color. Nickel plating is often used to provide a protective coating for other metals, and finely divided nickel is a catalyst for hydrogenating vegetable oils. It is also used in ceramics, in the manufacture of Alnico magnets, and in the Edison(R) storage battery.
Isotopes in Earth/Planetary Science
Because molecules, atoms, and ions of the stable isotopes of nickel possess slightly different physical and chemical properties, they commonly will be fractionated during physical, chemical, and biological processes, giving rise to variations in isotopic abundances and in atomic weights. There are measureable variations in the isotopic abundances of nickel in terrestrial silicate rocks (Fig. IUPAC.28.1) [228] B. Gueguen, O. Rouxel, E. Ponzevera, A. Bekker, Y. Fouquet. Geostand. Geoanal. Res.37, 297 (2013)..
Isotopes in Geochronology
Anomalies in 60Ni abundance caused by decay of now extinct 60Fe have been used to study the early history of our Solar System (see section 4.26.2). 59Ni is a cosmogenic radionuclide with a half-life of 7.6×104 years. Decay of 59Ni has been used to assess the terrestrial age of meteorites and to determine abundances of extraterrestrial dust in ice and sediment [230] G. F. Herzog, C. Schnabel, S. Xue, J. Masarik, R. G. Cresswell, M. L. D. Tada. Meteorit. Planet. Sci.33, A66 (1998)..
Isotopes in Industry
63Ni (with a half-life of 99 years) is produced from stable 62Ni and is a beta-emitting radionuclide that serves as an electron source together with 55Fe in electron-capture detectors. Electron-capture detectors are used as thickness gauges or as detectors for organic analytes in gas chromatography (Fig. IUPAC.28.2) [108] World Nuclear Association. Radioisotopes in Industry: Industrial Uses of Radioisotopes, World Nuclear Association (2014), Feb. 24; http://www.world-nuclear.org/info/inf56.html.. 63Ni is also used to ionize substances in ion mobility spectrometry–the basis of the instrument used in airports to screen passengers for drugs and bombs [231] J. R. Verkouteren, J. L. Staymates. Forensic Sci. Int.206, 190 (2011).. 63Ni is also used as a fluorescence-inducing source in elemental analysis by X-ray fluorescence spectroscopy and in miniaturized long-lived nuclear batteries [108] World Nuclear Association. Radioisotopes in Industry: Industrial Uses of Radioisotopes, World Nuclear Association (2014), Feb. 24; http://www.world-nuclear.org/info/inf56.html.. Until the mid-1980s, nuclear batteries were used in pacemakers, but then they were replaced by long-lasting lithium batteries [232] B. Ulmen, P. D. Desai, S. Moghaddam, G. H. Miley, R. I. Masel. J. Radioanal. Nucl. Chem.282, 601 (2009)..
Isotopes Used as a Source of Radioactive Isotope(s)
61Ni is used as a radiation target for production of the radioactive isotope 61Cu (with a half-life of 3.3 h), which emits positrons for positron emission tomography (PET) applications using the 61Ni (p, n) 61Cu reaction. 64Ni is used as a radiation target for production of 64Cu (with a half-life of 12.7 h), which is used in radioimmunotherapy by attaching it to an antibody for delivery of cytotoxic radiation (toxic to living cells) to a target cell via the 64Ni (p, n) 64Cu reaction [235] National Research Council. Isotopes for Medicine and the Life Sciences, p. 38, The National Academies Press, Washington, DC (1995).. 60Ni is used for the production of 57Co (with a half-life of 0.75 year), which is used as a reference source for gamma cameras that are used in nuclear medicinevia the 60Ni (p, 4He) 57Co reaction [235] National Research Council. Isotopes for Medicine and the Life Sciences, p. 38, The National Academies Press, Washington, DC (1995)..
Nickel chemistry is dominated by Ni²⁺, which forms many salts and coordination complexes. Nickel(II) oxide, NiO, is a green to black solid used in ceramics, catalysts, and battery materials. Nickel(II) sulfate, NiSO₄, is important in electroplating and hydrometallurgy. Nickel carbonyl, Ni(CO)₄, is a volatile zerovalent compound central to the Mond refining process and notable for its high toxicity. Nickel also forms sulfides, halides, organonickel complexes, and mixed oxides used as battery cathode precursors.
See more information at the Nickel compound page.
Nickel metal is not highly toxic as a solid, but nickel dusts, fumes, and soluble nickel salts can cause allergic contact dermatitis and respiratory sensitization. Some nickel compounds are classified as carcinogenic, especially with inhalation exposure in refining or processing environments. Nickel carbonyl, Ni(CO)₄, is acutely poisonous and readily absorbed by inhalation. Fine nickel powder can be a fire or explosion hazard.
Exposure to nickel metal and soluble compounds (as Ni) should not exceed 0.05 mg/cm3 (8-hour time-weighted average per 40-hour work week). Nickel sulfide fume and dust is recognized as being potentially carcinogenic.
Nickel is naturally present in rocks, soils, waters, and biological systems at low concentrations. Weathering releases Ni²⁺ and nickel-bearing particles, while industrial sources include mining, smelting, fuel combustion, waste disposal, and corrosion of alloys. Its mobility depends strongly on pH, organic matter, sulfide availability, and adsorption to iron and manganese oxides. Nickel is an essential trace nutrient for some microorganisms and plants, but elevated concentrations can be toxic.
Nickel is produced mainly from sulfide ores and lateritic ores. Sulfide concentrates are commonly smelted and refined, while laterites require energy-intensive pyrometallurgical or hydrometallurgical processing. Demand is strongly tied to stainless steel production and increasingly to battery materials, although cathode chemistry choices can change nickel intensity. Recycling from stainless steel scrap, superalloys, and batteries is economically important. Supply is influenced by ore type, energy cost, refining capacity, environmental controls, and the distribution of suitable deposits.
Nickel is found as a constituent in most meteorites and often serves as one of the criteria for distinguishing a meteorite from other minerals. Iron meteorites, or siderites, may contain iron alloyed with from 5 percent to nearly 20 percent nickel. Nickel is obtained commercially from pentlandite and pyrrhotite of the Sudbury region of Ontario, a district that produces about 30 percent of the world's supply of nickel.
Other deposits are found in New Caledonia, Australia, Cuba, Indonesia, and elsewhere.
Nickel is a relatively abundant iron-peak element made in late stellar burning and supernova nucleosynthesis. Radioactive ⁵⁶Ni, produced in explosive events, decays through ⁵⁶Co to ⁵⁶Fe and helps power the light curves of many supernovae. In planets, nickel partitions strongly with iron, so much of Earth’s nickel is thought to reside in the core, while accessible crustal nickel is concentrated by magmatic and weathering processes.
- Nickel was named from a troublesome copper ore that miners associated with a mischievous spirit.
- The kilogram was once defined by an alloy containing 90 percent platinum and 10 percent nickel.
- Nickel is one of the few elements ferromagnetic at ordinary temperatures.
- Raney nickel is a porous catalyst made by leaching aluminium from a nickel-aluminium alloy.
- Many meteorites contain iron-nickel metal rather than nickel as separate mineral grains.

Sources of this element.
Nickel is found as a constituent in most meteorites and often serves as one of the criteria for distinguishing a meteorite from other minerals. Iron meteorites, or siderites, may contain iron alloyed with from 5 percent to nearly 20 percent nickel. Nickel is obtained commercially from pentlandite and pyrrhotite of the Sudbury region of Ontario, a district that produces about 30 percent of the world's supply of nickel.
Other deposits are found in New Caledonia, Australia, Cuba, Indonesia, and elsewhere.
