Niobium Nb

Niobium, is a chemical element with symbol Nb and atomic number 41. 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 the element tantalum, and the two are therefore difficult to distinguish. Niobium products we provide:Niobium Metal:
