*In electronics industry, the addition of niobium oxide to the capacitor greatly improves the thermal stability of the capacitors. In addition, Nb2O5 is also widely used in piezoelectric ceramics,thermal ceramics,electromagnets,optical waveguides.

*Glass is a traditional application industry of Nb2O5, this is because when Nb2O5 added to glass, it have higher refractive index (Ta2O5 can be added to glass to raise refractive index, but because price is too high, can be used in the place with particularly high demand only), use extensively consequently optical glass, optical fiber, as well as coating material. As a glass additive, high requirements are required for coloring elements, such as Cr,Ni,Fe,RE, etc.


In sealed double polyethylene bags. The bags are packed in steel drums containing 50 Kgs net each.
