It is a soft, grey, ductile transition metal, which is often found in the pyrochlore mineral, the main commercial source for niobium, and columbite. The name comes from Greek mythology: Niobe, daughter of Tantalus since it is so similar to tantalum.Niobium has physical and chemical properties similar to those of the element tantalum, and the two are therefore difficult to distinguish." ] ,
