Niobium is a quite soft transition metal of light grey color. It is quite a rare metal. The origins of its name are believed to come from Greek mythology. This chemical element is especially valued for its corrosion resistance properties, so it is used in a few types of industries. Niobium is quite rare; it occurs in a few minerals and plays no important biological role. It is mainly used in alloys, especially with various steels, because it makes these alloys much stronger. They are used for producing rockets, engines, various kinds of pipes, oil rigs, and other similar kind of equipment.
