Niobium Pentoxide Powder
Niobium pentoxide is the inorganic compound with the formula Nb2O5. It is a colorless insoluble solid that is relatively unreactive. It is the main pioneer to all materials made of niobium, the dominant application is being alloyed, but other specialized applications include capacitors, lithium niobate, and optical glasses.
Niobium Pentoxide Powder Applications
Niobium pentoxide (Nb2O5) is used mainly in the production of niobium metal, but specialized applications exist for lithium niobate and as a component of optical glass.
