Niobium pentaoxide

Niobium pentaoxide, Nb205, also has a tendency to release oxygen into the gaseous phase upon heating [28], forming a colored substance that results from defects in the oxygen sub-lattice. [Pg.204]

Niobium pentaoxide is used for preparing many niobium salts, including niobium carbide (Balke process). It also is used in the aluminothermic process in the production of niobium metal. [Pg.634]

Niobium pentaoxide undergoes two important types of reactions, one is reduction to niobium metal or to lower oxides, and the other involves conversion of pentoxide to oxide trihalides when treated with halogens or hahdes. These reactions occur mostly at elevated temperatures. Reductions may he carried out hy carhon, hydrogen, niobium carbide, niobium metal, and other reducing agents at elevated temperatures and often in vacuum ... [Pg.634]
