Functions and Applications
Glass industry
Glass industry is a traditional Nb2O5 application industry, this is because the Nb2O5 added to the glass, make it has high refractive index (Ta2O5 added to the glass can increase the refractive index, but the price is too high, can only be used in special demanding place), and therefore is widely used in optical glass, optical fiber, as well as coating materials, etc As glass additives, demanding of colouring elements, such as Cr, Ni, Fe, RE, etc
