Nickel is a silver-white metal which occurs mainly in the sulphide and
arsenic ores. It is extracted by roasting to NiO and then reducing
using carbon. Pure nickel is manufactured by the Mond process, in
which impure nickel is reacted with carbon monoxide (CO) to produce
Ni(CO)4, which is then decomposed at 200C to yield 99.99% Ni.
Nickel has an abundance of 80 ppm in the earth's crust.
Pure nickel is malleable and ductile, and is resistant to corrosion in air or
water, and hence is used as a protective coating. It is readily
soluble in dilute acids, but is unaffected by alkalis. Applications
for nickel include its use as a constituent of various alloy types;
for example, Nichrome (an alloy used for resistance heating
elements), Monel (corrosion resistant material), Permalloy (an
alloy with high magnetic permeability at low field strength and low
hysteresis loss), stainless steel, cupro-nickel, nickel silver,
etc. It is also used in coinage, as a protective coating and within
food and chemical handling plants.
Nickel is classed as a carcinogen and is also an allergen to some
individuals. It is found in many dietary constituents and, as such,
is difficult to avoid.
