Product Details

Bismuth(III) Oxide CAS#1304-76-3

Bismuth(III) oxide is the compound produced by heating the metal, or its carbonate, in air. It is definitely a basic oxide, dissolving readily in acid solutions, and unlike the arsenic or antimony compounds, not amphiprotic in solution, although it forms stoichiometric addition compounds on heating with oxides of a number of other metals. It exists in three modifications, white rhombohedral, yellow rhombohedral, and gray-black cubical. Bismuth(II) oxide, BiO, has been produced by heating the basic oxalate.

Product Application of Bismuth(III) Oxide CAS#1304-76-3

Bismuth(III) oxide is used in the preparation of BiFeO3perovskite nanoparticles. It finds use in disinfectants, magnets, glass, rubber, vulcanization, fireproofing papers and polymers and catalysts. Bismuth trioxide brings about the "dragon's eggs" effect in fireworks, as a replacement of red lead. Bismuth(III) compounds are attractive reagents and catalysts in organic synthesis because of their low cost and ease of handling. Bismuth trioxide nanoparticles also play an important role in high energy gas generators. The alpha crystalline form of bismuth(III) oxide has p-type electronic conductivity.
