Description of Puratronic (metals basis)

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. Bismuth trioxide is commonly used to produce the “Dragon’s eggs” effect in fireworks, as a replacement of red lead.

What is Bismuth trioxide ?

• With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is Bismuth trioxide   which has developed particularly rapidly in recent years. Do you know about Bismuth trioxide?
• The official answer：Yellow monoclinic crystalline system. Soluble in acid, insoluble in water, and alkali. Can be reduced by carbon and hydrogen. Produced by heating decomposition of bismuth nitrate. Used in the production of bismuth metal, catalyst, and bismuth oxide superconductor. Bismuth oxide is also called “bismuth trioxide”, the pure product has α type, β type, and δ type. α type is yellow monoclinic crystal, relative density 8.9, melting point 825 ℃, soluble in acid, insoluble in water, and alkali. β type is a bright yellow to orange, square crystal system, relative density 8.55, melting point 860 ℃, soluble in acid, insoluble in water. Easily reduced to bismuth metal by hydrogen, hydrocarbons, etc. δ-Bi2O3 is a special material with cubic fluorite type structure, 1/4 of its crystal lattice is vacant in oxygen ion position, thus has very high oxygen ion conductivity.

What’s the application of Bismuth trioxide ?

• Used for making bismuth metal, catalyst and bismuth oxide superconductor use glaze drug, catalyst, rubber compound, medicine, red glass compound, and other uses. Use to make bismuth salt, pottery glaze. Clinical test sugar and alkaloids. High purity bismuth oxide used in: 1, electronic materials: including porcelain dielectric capacitors, piezoresistors, piezoelectric ceramics and other electronic components of the powder, adding ultra-fine bismuth oxide powder can greatly improve the relevant parameters, improve the performance of components; 2, ferrite magnetic materials, adding ultra-fine bismuth oxide powder can improve magnetic induction strength, magnetic permeability and magnetic flux density, optimize the performance of magnetic materials; 3, catalysts in the petrochemical industry, using its specific surface area, high activity, good selectivity, greatly improve the catalytic activity, effectively reduce production costs, and related passivators, additives, etc.; 4, color picture tube shade coating materials, can effectively prevent shade bulging; automotive top coat components, replace toxic metals, to achieve green; 5, glass, ceramic colorants, glazes, etc.; 6, high-performance bismuth silicate single crystal, bismuth-based high-temperature superconducting materials, high-quality optical glass, optical fiber, fireworks, new oxidation sensing material, fuel cell electrolyte, refillable alkaline zinc-manganese battery, flame retardant, clarifier, etc.; 7. Green environmental protection flame retardant, replacing toxic antimony-based flame retardant. 8. Additive for environmental protection battery, which can improve the performance of the battery.
