Main uses
It is mainly used in the chemical industry (such as chemical reagents, bismuth salt manufacturing, etc.), glass industry (mainly used for coloring), electronic industry (electronic ceramics, etc.). Among them, the electronics industry is the most widely used industry of bismuth oxide, mainly used in the fields of subresistors, thermistors, oxide lightning rods and picture tubes. In addition, Bi2O3 has a high refractive index and dielectric constant, significant fluorescence characteristics and inert water properties. Therefore, Bi2O3 is a visible light catalyst with great potential to decompose water and degrade pollutants
