Biography & contributions

Axel Fredrik Cronstedt was a Swedish mineralogist and chemist born on December 23, 1722 – died on August 19, 1765. Cronstedt was credited with the discovering nickel and scheelite and he is considered as one of the founders of modern mineralogy.

In 1756 Cronstedt coined the term zeolite and tungsten. He is also credited with developing an experimental procedure involving the systematic use of blowpipes for analyzing the chemical composition of minerals.

Facts about Nickel

Nickel is silvery-white, hard, malleable, and ductile metal. It is of the iron group and it takes on a high polish. It is a fairly good conductor of heat and electricity. Nickel is represented with symbol Ni, atomic number 28, atomic mass 58.6 g/mol, electron configuration [Ar] 3d8 4s2, density 8.908 g/cm3,melting point 1455 °C, boiling point 2730 °C.

Nickel is one of four elements that are ferromagnetic around room temperature. It is actually recovered through extractive metallurgy.

Nickel is used in many specific and recognizable industrial and consumer products, including stainless steel, alnico magnets, coinage, rechargeable batteries, electric guitar strings, microphone capsules, and special alloys. It is also used for plating and as a green tint in glass.

Nickel is preeminently an alloy metal, and its chief use is in the nickel steels and nickel cast irons, of which there are many varieties. It is also widely used in many other alloys, such as nickel brasses and bronzes, and alloys with copper, chromium, aluminium, lead, cobalt, silver, and gold.

Nickel is an excellent alloying agent for certain other precious metals, and so used in the so-called fire assay, as a collector of platinum group elements. Nickel and its alloys are frequently used as catalysts for hydrogenation reactions. Nickel is a naturally magnetostrictive material, meaning that, in the presence of a magnetic field, the material undergoes a small change in length.

Nickel is used as a binder in the cemented tungsten carbide or hard metal industry and used in proportions of six to 12 per cent by weight. Nickel can make the tungsten carbide magnetic and adds corrosion-resistant properties to the cemented tungsten carbide parts. Foodstuffs naturally contain small amounts of nickel. Chocolate and fats are known to contain high quantities of nickel.

Nickel uptake will boost when people eat large quantities of vegetables from polluted soils. Plants are known to accumulate nickel and as a result the nickel uptake from vegetables will be eminent. Smokers have a higher nickel uptake through their lungs.
