Everything About Nickel: History, Invention, A Few Vital Applications, Properties And Importance
Go to: Previous Article Next Article
For several thousands of years, men have used nickel in a lot of their needs. Previously, they weren't alert to the chemical properties of the component and that they could use nickel alloys in various purposes too.
What is nickel?
Nickel is a versatile metal, a chemical element, with an atomic number of 28 and chemical symbol Ni. It is glossy and sometimes silvery-white in appearance. It is a ferromagnetic element that can exist in normal temperature. There are only three other components that have the same characteristic: gadolinium, iron and cobalt.
How was nickel discovered?
It is believed that man has used nickel since 3500 BC. But, it was only in 1751 that it was classified and recognized as a chemical element by Swedish chemist & mineralogist Axel Fredrik Cronstedt who, at first, thought it was a copper mineral. From then, essential nickel ore minerals are discovered, such as limonite, pentlandite and garnierite.
What are the characteristics of nickel?
The characteristics of nickel are divided into atomic, physical, isotopes, and chemical. Its atomic properties include its electronic configuration, electron structure, and any other electron-related stuff.
Its physical characteristics include its color (which is silvery-white), magnetic abilities (like what was stated before, it is among the 4 elements which have magnetic abilities at room temperature, but is non-magnetic when open in temperature more than that), and unit cell structure (nickel has a face centered cubic unit cell). It's also ductile and hard.
Nickel has 5 stable isotopes, all of them has an unique set of properties and characteristics. And when we speak of nickel's chemical properties, it occurs in many oxidation states. The most typical among them all is +2.
Where is nickel used?
Many industries now make use of nickel in their operations. Some of the products that use nickel are rechargeable batteries, stainless steel, coinage, electric guitar strings, magnets, nickel alloys and other kinds of alloys, including bronze, copper, lead, silver, gold, cobalt, aluminum & chromium. It's also used to make nickel cast irons and nickel steels.
Nickel alloys are normally used in power plants, gas and oil plants, and any other processing factories. They're excellent at corrosion resistance and heat regulation. They are also utilized in nuclear reactors and solar engineering. In our home, nickel alloys are found in our electrical heaters, cookers and any other appliance.
