Product Description

High Purity Bismuth Trioxide with CAS No. 1304-76-3

Product Overview

Bismuth Trioxide, also known as antimony trioxide, it is yellow powder that is insoluble in water and soluble in strong acids to form Bismuth (III) salts. Its melting point is 824 ° C, Its boiling point is 1890 ° C. It is one of the most important compounds and can be reduced to metal ruthenium by hydrogen. Although antimony trioxide can be obtained from natural alfalfa (a mineral), its main source is usually a by-product of copper or lead, and the tantalum powder can be burned in the air to obtain antimony trioxide. It is mainly used in the chemical industry (such as chemical reagents, barium salt manufacturing, etc.), glass industry (mainly used for coloring), electronics industry (electronic ceramics, etc.). Among them, the electronics industry is the most widely used industry for Bismuth Trioxide, mainly used in varistor, thermistor, oxide arrester and picture tube. In addition, Bismuth Trioxide has a high refractive index and dielectric constant, remarkable fluorescence characteristics, and water repellency. Therefore, Bismuth Trioxide is a promising visible light catalyst for decomposing water and degrading pollutants.
