Anwendungen

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 generator. The alpha crystalline form of bismuth(III) oxide has p-type electronic conductivity.

Bemerkungen

Incompatible with materials like strong oxidizing agents.
