Bismuth oxide powder, Bi2O3:

Bismuth Trioxide and Bismuth Oxide are inorganic compounds with the molecular structure Bi2O3. There are three types of pure products: type a (monoclinic crystal), type b (molecular formula Bi2O3), and type d (pure product). A type is a yellow monoclinic, yellow-colored crystal with an 8.9 relative density and an 825 melting point. This product is stable in acids but not in water or alkali. B-type, which is brightly yellow to orange, has an 8.55 relative density and melts at 860. Soluble in acid. Insoluble in water. You can easily reduce it to bismuth by using hydrogen or hydrocarbons. d-Bi2O3 (cubic fluorite) is a unique material that has high oxygen conductivity. The main uses of bismuth dioxide include electronic ceramic powder, photoelectric, ultraconducting, and high-temperature superconducting material, as well as catalysts. Bioxide is an essential additive to electronic ceramic powder materials. Purity is usually required to exceed 99.15%. Main application objects include zinc oxide varistor (ceramic capacitor) ferrite magnetic material in three types.

The atmospheric or water-soluble carbon dioxide forms bismuth subcarbonate when it reacts with Bi2O3. Bismuth oxide is an alkaline ox, which explains its high reaction with carbon dioxide. However, if an acidic compound, such as Si(IV), is added to the bismuth oxide structure, it does not react with carbon dioxide.

Bismuth oxide powder performance:

Pure trioxide products have two types. A yellow monoclinic crystal of a type has a relative density of 8.9 with an 825°C melting point. It is insoluble in acid and insoluble in water. The b-type, which is bright yellow or orange and cubic crystal systems, has a relative density of 8.55 and a melting point of 860. It's soluble/insoluble in acid. Hydrocarbons and hydrogen can easily reduce this to make metallic bismuth.

How Bismuth Oxide bi2O3 Powder is produced?

Metal bismuth oxidation method: the metal bismuth is placed in oxygen and heated to a high temperature to obtain bismuth oxide. This method is simple and feasible, but it requires high-purity metal bismuth raw material, the reaction temperature is high, and the energy consumption is large.

Bismuth hydroxide method: Bismuth hydroxide and nitric acid reaction to produce bismuth nitrate solution, and then add ammonia water reaction to produce bismuth hydroxide precipitation, after washing, drying to obtain bismuth oxide product.

Chlor-alkali process: the reaction of chlor-alkali and bismuth nitrate to produce bismuth hydroxide precipitation after washing and drying to obtain bismuth oxide products.

Ion exchange method: The solution containing metal ions is mixed with the solution containing bismuth oxide ions, and the bismuth oxide precipitation is generated through the ion exchange reaction. After filtration, washing, and drying, high-purity bismuth oxide products were obtained.
