CAS 7440-03-1: Niobium

Description:Niobium, with the chemical symbol Nb and CAS number 7440-03-1, is a transition metal known for its high melting point and excellent corrosion resistance. It is a silvery-gray metal that is ductile and can be easily shaped. Niobium is primarily used in the production of high-strength steel alloys, which enhance the strength and toughness of materials used in construction and manufacturing. It has a body-centered cubic crystal structure and exhibits superconducting properties at low temperatures, making it valuable in applications such as MRI machines and particle accelerators. Niobium is also resistant to oxidation and can form a protective oxide layer, which contributes to its durability in various environments. Additionally, it is relatively rare in the Earth's crust and is primarily obtained from minerals such as columbite and pyrochlore. Due to its unique properties, niobium plays a significant role in modern technology and materials science.
