Nickel is a chemical element (Ni )and atomic
number is 28. It is a silvery-white lustrous metal.Nickel belongs to the transition metals and it is hard and
ductile. Pure native nickel is found in Earth's crust only in small amounts. Nickel
was first discovered and classified as a chemical element in 1751 by Axel
Fredrik Cronstedt, Nickel ores are mined in 23 countries
Nickel is slowly oxidized by air at room temperature and is
considered corrosion-resistant. it has been used for plating iron and brass,
coating chemistry equipment, and manufacturing certain alloys that retain a
high silvery polish, such as German silver.Nickel is one of the most widely used metals on the planet.
According to the Nickel Institute, the metal is used in over 300,000 different
products. Most often it is found in steels and metal alloys, but it is also
used in the production of batteries and permanent magnets.Nickel is one of four elements (the others are iron, cobalt,
and gadolinium) that are ferromagnetic at approximately room temperature.
Nickel occurs less abundantly than cobalt. It is found in
mainly in combination with arsenic ,antimony and sulphur
Main ores of Nickel: pentlandite, copper,iron.
It has melting point about 1453 degree c. It has high electrical
and thermal conductivity. It is used in the making of spatulas, crucibles and
tongs .
