Niobium Pentoxide (Nb2O5)-Powder introduce:
Niobium pentoxide is the inorganic compound with the formula Nb2O5. It is a colourless insoluble solid that is fairly unreactive. It is the main precursor to all materials made of niobium, the dominant application being alloys, but other specialized applications include capacitors, lithium niobate, and optical glasses.
Molar mass：265.81 g/mol
Appearance：white orthogonal solid
Melting point：1,512 °C (2,754 °F; 1,785 K)
Solubility in water：insoluble
Solubility：soluble in HF
Niobium pentoxide is used mainly in the production of niobium metal, but specialized applications exist for lithium niobate and as a component of optical glass.
Thin films of Nb2O5 form the dielectric layers in solid electrolyte capacitors.
