It is mainly used in chemical industry (such as chemical reagent, bismuth salt manufacturing, etc.), glass industry (mainly used for coloring), electronics industry (electronic ceramics, etc.), etc. Among them, electronic industry is the industry with the most extensive application of bismuth oxide, which is mainly used in such fields as pressure sensitive resistance, thermal sensitive resistance, oxide arrester and picture tube. In addition, Bi2O3 has high refractive index and dielectric constant, significant fluorescence characteristics and inert water. Therefore, Bi2O3 is a promising visible light catalyst for water and pollutant degradation.
