  • Melting and purification of niobium

    Melting and purification of niobium

    carbon residuals may turn niobium into a hard and brittle material3. Furthermore, for some special applications such as superconductivity, only a few ppm of most impurities are tolerable. In order to produce high purity niobium ingots, electron beam melting has proven to be the most suitable process.
