niobium processing | History, Ores, Mining, & Extraction ...

Niobium processing, preparation of niobium ore for use in various products. Niobium (Nb) has a body-centred cubic (bcc) crystal structure and a melting point of 2,468 °C (4,474 °F). Of the refractory metals, it has the lowest density and best workability; for this reason, niobium-based alloys are often used in aerospace applications.
