Applications of Niobium Semi-Finished Products
Niobium belongs to the family of refractory metals and is extracted from the ores columbite, coltan, and loparite. Primarily, niobium is used as an alloying element for special stainless steels.
Niobium and its alloys are highly versatile as metallic semi-finished products. Due to its excellent corrosion resistance, which is almost comparable to tantalum, it is widely used in highly corrosive applications within the chemical industry. Other applications include cavities made from high-purity niobium for accelerator facilities, such as the XFEL DESY in Hamburg.
Niobium and niobium alloys are also used in medical technology (MRI), the coating industry (technical layers), the lamp industry (sodium vapor lamps), and aerospace applications (control nozzles).
Production of Niobium Semi-Finished Products
Due to the complex extraction and challenging production processes of metallic niobium semi-finished products, the material is expensive and only available in limited quantities.
However, processing niobium semi-finished products is not difficult. The material is relatively soft, ductile, and easy to form. It can also be welded well and safely, provided its affinity to gases is considered. During mechanical processing, it is important to note that the material does not produce coarse chips and tends to lubricate.
For high-temperature applications in air or oxidizing atmospheres, niobium alloys must be specially coated. Otherwise, they react immediately with oxygen, leading to the formation of Nb2O5, which will eventually degrade the material.
