Bismuth Oxide Powder

Bismuth oxide, also known as bismuth trioxide, is yellow powder, insoluble in water and soluble in strong acid to form bismuth (III) salt. The product features high purity, small particle size, uniform distribution, large specific surface area, high surface activity, low bulk density; insoluble in water, soluble in strong acid to form bismuth salt.

It is mainly used in chemical industry (such as chemical reagent, bismuth salt manufacturing, etc.), glass industry (mainly used for coloring), and electronic industry (electronic ceramics, etc.). Among them, the electronic industry is the most widely used industry of bismuth oxide, mainly used in varistor, thermistor, oxide arrester, picture tube and other fields. In addition, Bi2O3 has high refractive index and dielectric constant, remarkable fluorescence characteristics and inert water property. Therefore, Bi₂O₃ is a potential visible light catalyst for water decomposition and pollutant degradation. The purity is up to 99.99% and 99.999%. Get a Quote Now!
