Niobium applications include sputtering targets, nuclear reactors, gas pipelines, jet engines, chemical processing equipment, particle accelerators, turbine blades, automotive components, capacitors, superconductors, sensitive magnetic imaging equipment, vacuum furnaces, reactor vessels, heat exchangers, sodium lamps, jewelry, steel additive, and optics.

Niobium is less corrosion-resistant than tantalum at high temperature. Niobium is not attacked by nitric acid up to 100 °C, but aggressively attacked by mixture of nitric and hydrofluoric acids. Hot, concentrated hydrochloric, sulfuric, and phosphoric acids attack it, but hot, concentrated nitric acid does not. Niobium is unaffected at room temperature by most acids. It is attacked by alkaline solutions to some extent at all temperatures.  Due to its low capture cross section for thermal neutrons, Niobium has application in the nuclear industry. Niobium can be electrically heated and anodized to a wide variety of colors that makes it very attractive in the jewelry industry.
