Chromium is valued as an important strategic mineral for a nation’s sovereignty. Chromium is the only element which shows antiferromagnetic ordering in its solid state at and below room temperature. Simple polished chromium reflects almost 70% of the visible spectrum, with almost 90% of infrared light being reflected. The weapons of the famous Terracotta Army of the Qin Dynasty in China were tipped with chromium deposits, which helped prevent tarnishing. He produced chromium oxide (CrO. ) It’s Used in Stainless Steel.

Chromium is used to prepare pigments (including yellow, red, and green), to color glass green, to color rubies red and emeralds green, in some tanning processes, as a decorative and protective metal coating, and as a catalyst. The word “Chromium” comes from the Greek word for color (“chroma”), reflecting the colorful nature of chromium compounds and the popularity of its pigments. Although it is rare, native chromium also exists. It is the most popular element for sheet coating. Because of its hardness and resistance to corrosion chromium is u. sed for surface coating.
