Bismuth(III) oxide - Wikipedia

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 (monoclinic) and sphaerobismoite (tetragonal, much more rare), but it is usually obtained as a by-product of the smelting of copper and lead ores. Dibismuth trioxide is commonly used to produce the "Dragon's ...

Release kinetics and distribution of lead in various size ...

Pb fractions in soils and soil aggregates. Lead was fractionated into soluble and exchangeable (F1), carbonate bound (F2), Fe–Mn oxide–bound (F3), and organic-bound (F4) by Tessier's method (Tessier et al. 1979 ). The residual fraction of Pb (F5) was determined by Sposito's method (Sposito et al. 1982 ).
