Bismuth trioxide

CAS: 1304-76-3
Molecular Formula:  Bi2O3
Molecular Weight: 465.96
Product description:Refinement are alpha, beta, and delta type. For yellow monoclinic system crystalline alpha type, relative density 8.9, melting point 825 ℃, soluble in acid, insoluble in water and alkali. Beta is bright yellow to orange, tetragonal crystal system, relative density 8.55, melting point 860 ℃, soluble in acid, insoluble in water. Easy to hydrogen and hydrocarbons such as reduction of metal bismuth. The delta - Bi2O3 is a kind of special material, with cubic fluorite ore type structure, a quarter of oxygen ion in the crystal lattice position is vacant, thus has very high oxygen ionic conductivity. Bismuth oxide is mainly used objects have electronic ceramic powder materials, electrolyte materials, photoelectric materials, high temperature superconducting materials, catalysts. Bismuth oxide as an important additive in electronic ceramic powder materials, general requirements in more than 99.15% purity, main application object has zinc oxide varistor, three types of ceramic capacitors, ferrite magnetic materials.
