: Niobium is used as an alloying agent and for jewelry. Other uses include adding small amounts to improve stainless steel, as an alloying agent in carbon and alloy steels and in non-ferrous metals to improve strength.

: Niobium is a silver coloured metal which is generally found in conjunction with tantalum, the two elements being separated by fractional crystallisation of their respective fluoro-complexes. It has an abundance of 20 ppm in the earth's crust. As a pure metal, is very reactive and forms an extremely stable oxide when exposed to air which enhances its corrosion resistance. Niobium will react with a variety of non-metals at elevated temperatures.
