Description
Bismuth(III) 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 and sphaerobismoite, but it is usually obtained as a by-product of the smelting of copper and lead ores.
