The element chromium is a metallic element with atomic number 24 and atomic weight 51,996. Its Latin is Chromium and its symbol is Cr. Chromium is in the 5B area of the periodic table.
The chrome element, which is especially used in the chrome plating process, has found its use in the industrial field in the 20th century. Its most important feature in the industrial sector is that its melting point reaches 1890 ° C, while its boiling point reaches up to 2500 ° C.
The first person to discover chromium was a French chemist named Vauquelin. During his research in Siberia in 1797, he found it in a Lead sprout. Chromium is among the first crystallized elements in the formation of the world. Chrome stone, rock, etc. It is found in crystal form in places and it is delivered to production facilities as powder or liquid during its processing.
Since the color of each compound is different, it is used in a wide range of paint industry as well as in hard chrome plating on steel or metal. While Cr +2 compound is blue in color, Cr +3 Green, Cr +6 and +7 can be yellow, red and orange. They are used to color the paint with the necessary solutions.
Chromium is an element hidden from the earth, between stones and in rocks and is not found in pure form. It is in combination with other natural elements. After necessary procedures, it is purified and sold to the market. Formation of chromium element in nature is in the form of chromite and its formula is FeOCr2Os3.
In metal industry (to produce stainless products, to provide corrosion resistance, to provide hard strength), to provide the necessary reactions in the field of chemistry and to produce a new formula (coloring paint, etc.) and the most important area of use is in stainless steels with Ni. The chromoxide layer it creates covers the steel surface like a film layer and provides resistance to chemical corrosion.
It is a very important element for operators in businesses due to its properties in industrial solutions.
There are chrome deposits in Mersin, Adana, Kayseri, Bursa, Balıkesir, Kütahya, Kocaeli, İstanbul, Yalova and İzmit. The chromium element helps transfer the sugar in the blood to the cells. Chromium is also found in peanuts, egg yolks, cheese, grape juice, yeast, oysters. It also benefits bones.
