Nb has a small neutron capture cross section, high thermal conductivity and high strength, and is used as a nuclear fuel jacket material, a nuclear fuel alloy additive, and a heat exchanger structural material in an atomic energy reactor. Metallurgical grade niobium powder is mainly used as an additive for alloys and for producing welding electrodes and refractory materials. Niobium bars are mainly used in the production of special steel and superalloys, magnetic materials and other niobium alloys in the steel industry.
