ECHEMI Editorial Reference

Bismuth oxide is an inorganic compound, odorless, stable in the air, with a molecular formula of Bi2O3. The pure products are α-type, β-type and δ-type. α-type is a yellow monoclinic crystal with a relative density of 8.9 and a melting point of 825 ℃. It is soluble in acid but insoluble in water and alkali; β-type is a bright yellow to orange tetragonal crystal with a relative density of 8.55 and a melting point of 860 ℃. It is soluble in acid but insoluble in water. It is easily reduced to metallic bismuth by hydrogen, hydrocarbons, etc.
