Bismuth Oxide Pellet Evaporation Material (Bi2O3)

Bismuth oxide is perhaps the most industrially important compound of bismuth. It is also a common starting point for bismuth chemistry. It is found naturally as the mineral bismite(monoclinic) and sphaerobismoite (tetragonal, much rarer). But it is usually obtained as a by-product of the manufacturing of copper and lead ores. Bismuth trioxide is commonly used to produce the "Dragon's eggs" effect in fireworks, as a replacement of red lead.
