NIOBIUM – A material for innovations with great future potential
Niobium is a light gray metal with a gleaming white appearance on polished surfaces. It is characterized by a high melting point of 2,477°C and a density of 8.58g/cm³. Niobium can be easily formed, even at low temperatures. Niobium is ductile and occurs with tantalum in a natural ore. Like tantalum, niobium also features outstanding chemical and oxidation resistance.
A multi-talented material for optical applications, electronics and superalloys
Its combination of unique chemical and physical elements makes it particularly suitable for a wide variety of challenging high technology applications:
- H.C. Starck's niobium oxides have a high degree of chemical purity and are used in the optical industry in the production of lenses for glasses and components for digital cameras
- AMPERLOY® nickel niobium is used as an additive for superalloys to improve special steels. AMPERLOY® nickel niobium improves resistance to high temperatures as well as tensile loading and shocks due to vibration or impact
- Niobium has superconducting properties at very low temperatures. For this reason, it is designated for use in the construction of particle accelerators
- Niobium makes optical surfaces anti-reflective and simultaneously increases scratch resistance. Application examples here include touchscreens, monitors and optical lenses
- Single crystals grown from lithium niobate are the base material used in radio frequency filters (SAW filters), which allow mobile communication and wireless data transfer without disturbance
- Niobates, niobium oxalates and niobium chlorides produced by H.C. Starck are used as dopants for electroceramics and piezo ceramics, catalysts, ferrites and pigments
- The stability of hard metal cutting tools is improved with niobium carbide, resulting in higher operating efficiency.
