Niobium is a light gray material with a lustrous white appearance on polished surfaces. The metal has a density of 8.58 g/cm³ and a high melting point of 2,477 °C. It has good formability even at low temperatures. The ductile material often accompanies with tantalum in a natural ore and demonstrates excellent oxidation and chemical resistance like tantalum. It is a material for innovations with very high future potential.
Applications of Niobium
Niobium’s unique combination of physical and chemical elements makes it a material of choice in a myriad of challenging high technology applications such as electronics, optics and superalloys. It demonstrates superconducting properties at very low temperatures, which make it suitable for use in particle accelerator construction. Niobium carbide improves operating efficiency of hard metal cutting tools by increasing their stability.
Niobium not only imparts anti-reflective properties to optical surfaces, but also optimizes their scratch resistance. This quality makes it useful in applications such as optical lenses, monitors, and touchscreens, to name a few. Single crystals grown from lithium niobate are used as the base material for radio frequency filters or SAW filters, which facilitate wireless data transfer and mobile communication without disruption.
