Advanced information and preparation of bismuth oxide

Bismuth oxide is a pale yellow powder at room temperature, orange when heated, and continues to be heated to reddish brown, which still becomes light yellow after cooling. Bismuth oxide is insoluble in alkali and water, but soluble in acid to form phosphonium salt. It is easily reduced by C and CH 4. It has a melting point of 824°C and a boiling point of 1890°C. Cerium oxide mainly exists in four crystal forms: α, β, γ and δ, among which α-BiO 3 is monoclinic, β-BiO3 is tetragonal, and α-Bi2O3 and β-Bi2O3 are cubic crystals. . Each crystal type of yttrium oxide has its own special structure and properties. For example, due to the phase composition, the band gap can be changed from 2 eV to 3.96 eV, where the band gap of the α phase is 2.85 eV and the band gap of the β phase is 2.58 eV.

The density of yttrium oxide also changes with the crystal type: monoclinic crystal is 8.2 g·cm 3, tetragonal crystal is 8.55 g·cm 3 and cubic crystal is 8.9 g·cm 3. The monoclinic structure of α-BiO3 is a low temperature stable phase, while the cubic structure of δ-BiO3 is a high temperature stable phase, and the other two crystal types are metastable crystal types.

Overview of bismuth oxide Bi2O3 powder

Bi2O3 bismuth oxide powder is one of the most important bismuth compounds. It has excellent dielectric properties, high oxygen fluidity, large energy gap, high refractive index, significant photoconductivity and photoluminescence. It is an advanced functional material ;

Pure bismuth trioxide has α type and β type. The α type is yellow monoclinic crystal, the relative density is 8.9, and the melting point is 825°C. Soluble in acid, insoluble in water and alkali. β type is bright yellow and orange, cubic crystal system, relative density 8.55, melting point 860°C, soluble in acid but insoluble in water. Easily reduced to metallic bismuth by hydrogen, hydrocarbons, etc.
