Corrosion of Niobium and Niobium Alloys

For chemical processing, niobium resists a wide variety of corrosive environments, including mineral acids, many organic acids, liquid metals, and most salt solutions. This article focuses on the mechanisms of corrosion resistance of niobium alloys in these environments. The niobium alloys include Nb-1Zr, Nb-55Ti, Nb-50Ta, and Nb-40Ta. The article describes the use of these corrosion resistant niobium alloys, and provides information on applications of niobium in various industries.
