Bismuth Oxide Bi2O3 Powder Supplier

What Is Bismuth Oxide Bi2O3? Bismuth triooxide ( Bismuth oxide ) is an organic compound having the molecular structure Bi2O3.

The chemical formula is Bi2O3.

Molecular weight 465.96

Properties: Yellow heavy powder, monoclinic crystal. Odorless. Stable in the atmosphere


Melting point (degC): 825

Boiling Point (degC; atmospheric pressure): 1890

Solubility. It’s soluble and insoluble with hydrochloric acid or nitric, but not in water. It becomes maroon upon heating and turns yellow when chilled.

Pure products are classified as a type, type b, and type d.

This is a type of that’s a yellow monoclinic, monoclinic crystal. It has a relative density of 8.9 with a melting temperature of 825. It is insoluble in acid, and soluble in water.

Types b are bright yellow or orange in color. They have a square system with a relative density of 8.55, melting temperature 860 and are soluble/insoluble in acid. This can be easily reduced to metal bismuth with hydrogen or other hydrocarbons.

–Bi2O3 This is a unique material that has cubic fluorite structures and high oxygen conductivity.

Electronic ceramic powder, electrolyte, optoelectronic, superconducting, high-temperature catalysts and electronic ceramic powder are all common uses for bismuth. Bismuth dioxide is an important ingredient in electronic ceramic material, and has a purity higher than 99.15%. It’s used primarily in zirconium oxide varistors, ceramic capacitors, and ferrite magnetic material.

What does Bismuth Oxide Bi2O3 serve?

The important metal-oxide semiconductor Bismuth dioxide (Bi2O3) has been a hot topic because of its exceptional optical and electrical properties. These include a wide band gap, high permittivity, and photoconductivity.

Bismuth oxide’s unique characteristics have been explored and utilized in numerous fields including fuel cells, sensor technology and oxide varistors. The manufacturing of transparent ceramic glasses, optical coatings, ceramics, and catalysts is all dependent on bismuth oxide. The industrial sector based on Bi2O3 manufacturing tech has seen great advancements due to the manufacture of many high-quality optical fibers like erbium doped (Er), bismuth oxid fiber, or highly nonlinear bismuth oxide fiber.

The nonlinearity of Bi2O3 fibers is 200x greater than the SiO2 and is therefore attractive. This nonlinear phenomenon plays a crucial role in ultrafast optical transmitting systems and all optical transmission networks. It can therefore be studied for all optical processing subsystems such as logic gates, regenerators and demultiplexers. Bi2O3 semiconductors have advantages in compactness, integration and dynamic limitation by charge carriers (hundreds and picoseconds).

Bismuth Oxide Acidic Or Basic?

Pure Bi2O3 can be found in both alkaline and acidic locations, similar to TiO2, SnO2 & Fe2O3, but it is much more alkaline that these oxides.
