High purity niobium pentoxide (Nb2O5) is an important raw material for a large number of advanced technological applications. High purity niobium pentoxide (>99.99%) is used in the production of lithium niobate single crystals for application in surface acoustic wave devices for TV receivers. 99.9% Nb2O5 is used for the production of optical lenses, for ophthalmic, microscopes and video camera lenses, and niobium containing ceramic condensers and actuators. Other than the applications in fine ceramics, niobium pentoxide is the raw material for the production of different purity grades of niobium metal. Technical grade niobium pentoxide is used for the preparation of niobium carbide which is being used in cutting tool industry.

Key features
