General
- Nickel is a metallic chemical
element with the symbol Ni and atomic number 28.
- Nickel is a silvery-white metal
that takes on a high polish. It belongs to the transition metals, and is
hard and ductile.
- Nickel is used in many industrial
and consumer products, including stainless steel, magnets, coinage, and
special alloys. It is also used for plating and as a green tint in
glass.
- Nickel is magnetic, and is very
often accompanied by cobalt, both being found in meteoric iron.
- Nickel is a hard, silvery white
metal. It is produced by mining and refining sulphide and oxide ores.
Nickel is also recycled from scrap metal.
Application
- Nickel based super alloys are used
within the industrial gas turbine (IGT) engine manufacturing industry,
specifically to meet the needs of the hot gas path components and the
applications have been heat treated to improve resistance to
creep.
- The application of a chelating
nickel citrate precursor results in the deposition of a thin film
strongly fixed to the mesopore surface.
- The application of High purity
nickels are used in electronic and aerospace applications, chemical and
food processing equipment, for anodes and cathodes, caustics evaporators
and heat shields.
- The application of zinc based
coatings to protect ferrous substrates from the effects of corrosion are
well established in the surface coatings industry.
- The autocatalytic electroless
nickel-phosphorous deposits have wide range of commercial applications
because of their wear and corrosion resistance, adaptability for uniform
coating on complex shapes.
Technology
- The technique for determining
nickel in serum by flameless atomic absorption, with use of
dimethyiglyoxime.The procedure permits a greater number of
analyses per technicianat a relatively low cost, yet provides acceptable
accuracy and reliability.
- In the ever reducing gate
dimension and junction depths, nickel Silicide has become one of the
promising candidates for silicides applications in submicron CMOS
devices.
- The technique that was used to
determine the sheet resistance of the nickel Silicide NiSi film was by
using the four-point probe technique where a current is run two outer
probes and measure the resulting voltage between the two inner
probes.
Process
- The duplex, semi-bright nickel,
bright nickel or chromium, KI’s metal plating process adheres to the
same rigid quality standards that permeate the entire
organization.
- Nickel is commonly used in
electroplating. Electroplating is the process by which a thin layer of
one metal is laid down on top of a second metal.
- The DON process is a shorter and
more flexible version of the early nickel flash smelting process chain
the DON process enables high recovery of nickel and copper, since there
is no unnecessary internal material circulation.
Market
- According to traders, demand for
nickel pig iron from stainless steel makers is growing at annual rate of
50 percent and it shall continue exerting downward pressure on
nickel prices.
- CIS countries are the largest
producers of mined nickel and contribute to about 19.77% of the world
production.
the growth of low nickel austenitic stainless steels (200
series) which are replacing the 18%Cr-8%Ni steels and the stainless
steel scrap availability that could bring a balance in the nickel
market.
- Nickel consumption is derived from
the production growth of austenitic stainless steel in the world as this
segment consumes 68% of the nickel produced.
- According to traders, demand for
nickel pig iron from stainless steel makers is growing at annual rate of
50 percent and it shall continue exerting downward pressure on nickel
prices.
