Chromium

Chromium is a chemical element with the symbol Cr and atomic number 24. It is the first element in group 6. It is a steely-grey, lustrous, hard, and brittle transition metal. Chromium is the main additive in stainless steel, to which it adds anti-corrosive properties. Chromium is also highly valued as a metal that is able to be highly polished while resisting tarnishing. Polished chromium reflects almost 70% of the visible spectrum, with almost 90% of infrared light being reflected. The name of the element is derived from the Greekwor

Chromium Plansee

Chromium is a lightweight blue-silvery white metal. The name chromium comes from the Greek "chroma" and means color.Thanks to its very high corrosion resistance against many different acids and bases as well as hot gases, chromium is a popular material for all types of protective coating. In combustion equipment, chromium is used as a wear-resistant coating to increase the service life of

Metal Profile: Chromium Properties, History & More

Feb 03, 2019 Aluminothermic production of high purity chromium metal accounts for over 95% of chromium metal produced today. The first step in this process requires that the chromite ore is roasted with soda and lime in the air at 2000°F (1000°C), which creates a sodium chromate containing calcine.It can be leached away from the waste material and then reduced and precipitated as chromic oxide (Cr

5 Uses of Chromium Uses of Chromium in Industry
