Bismuth trioxide is an inorganic compound, the chemical formula Bi2O3, is one of the most important compounds of bismuth, although bismuth trioxide can be obtained naturally from bismuth (a mineral), but its main source is usually copper or lead smelting byproduct, or directly burning bismuth (blue flame).Bismuth oxide is also known as "bismuth trioxide", pure products are α, β and δ types. α type is yellow monoclinic crystal system, relative density 8.9, melting point 825ºC, soluble in acid, insoluble in water and alkali. β type is bright yellow to orange, tetragonal crystal system, relative density 8.55, melting point 8Chemicalbook60ºC, soluble in acid, insoluble in water. It is easy to be reduced to metal bismuth by hydrogen and hydrocarbons. Delta-bi2o3 is a special material with a cubic fluorite type structure, in which 1/4 of the oxygen ion position is vacant in the lattice, and thus has very high oxygen ion conductivity.
