Niobium (Nb) is a refractory transition metal prized for its high melting point, corrosion resistance, and ability to form stable compounds with other elements. It is widely used in superalloys for aerospace engines, structural components in nuclear reactors, and superconducting applications, where its combination of strength at elevated temperatures and chemical stability outweigh the drawbacks of higher density and cost compared to more common structural metals.
