Hazard Information | Back Directory | [Chemical Properties]
white crystalline powder | [Physical properties]
White orthogonal crystals; density 4.60 g/cm3; melts at 1,512°C; insoluble in water; soluble in hydrofluoric acid. | [Application]
Niobium(V) oxide is used in metallurgy, electronics, optics, and the production of hard materials. Applied in the solid state formation of an unusual cation deficient perovskite, Ba7Nb4MoO20. Promising results were obtained using niobium(V) oxide as an alternate electrode to lithium metal in advanced fuel cells. Niobium Oxide (Nb2O5) is a new electrode material with pseudocapacitive charge storage being introduced to the market for the first time as a potential anode material. | [Preparation]
Niobium pentoxide is produced as an intermediate during recovery of Nb metal from ores (See niobium). Also, the pentoxide may be produced by igniting niobium metal powder, niobium carbide, or niobium fluoride in oxygen. | [Health Hazard]
Niobium pentoxide (Nb2O5) increases both the refractive index of optical glasses and the capacity of multi-layered ceramic capacitors (MLCCs). In contrast to lead oxide, niobium pentoxide poses no health risks.
| [Flammability and Explosibility]
Nonflammable | [Toxics Screening Level]
The screening level for niobium oxide is 0.1 μg/m3 based on annual averaging. |
