CAS 7440-47-3
:Chromium
Description:
Chromium, with the CAS number 7440-47-3, is a transition metal known for its high corrosion resistance and hardness. It has an atomic number of 24 and is represented by the symbol Cr on the periodic table. Chromium exhibits a silvery-gray metallic luster and is primarily found in nature in the form of chromite ore. It is characterized by its ability to form various oxidation states, with +3 and +6 being the most common in compounds. Chromium is widely used in the production of stainless steel and other alloys, enhancing their strength and resistance to oxidation. Additionally, it plays a crucial role in the manufacturing of pigments, such as chromium oxide, which imparts vibrant colors to ceramics and paints. In terms of chemical reactivity, chromium can react with oxygen and other nonmetals, forming oxides and other compounds. While essential in trace amounts for biological functions, certain chromium compounds, particularly hexavalent chromium, are known to be toxic and carcinogenic, necessitating careful handling and regulation.
