The Applications of Bismuth Oxide

The price of nickel and stainless steel rose together. Nickel afternoon hand in hand with stainless steel together turn red up. Due to the temporary easing of geopolitical risks, risk assets are now picking up, nonferrous metals, stock markets, and so on have risen, the overall mood has temporarily improved. Ore prices are strong, the overlay of the epidemic on spot logistics or the formation of a certain impact. Phase, nickel and stainless steel materials to maintain high wide concussion pattern.

Nickel prices based on low inventory, tight supply and demand will still show high wide fluctuations. In addition, the current LME has low liquidity, so its sensitivity to capital will remain relatively high. Shanghai nickel-wide fluctuations are expected to continue in the 200,000-250,000 yuan wide repeated fluctuation trend. While stainless steel is affected by the stronger nickel pig iron, the cost support continues, but note that under the current demand is not effectively released, the upward space may also be affected, the stage is expected to fluctuate between 20000 and 22,000 yuan. The price of nickel produced such fluctuations, indicating that the price of the Bismuth Oxide may also be affected to a certain extent.


What is Bismuth Oxide 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, and is an advanced Functional materials;
The pure product of bismuth trioxide has α type and β type. The α type is yellow monoclinic crystal with a relative density of 8.9 and a melting point of 825°C. Soluble in acid, insoluble in water and alkali. β type is bright yellow to 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.
The main features of Bismuth Oxide Powder
Bismuth oxide is an important additive in electronic ceramic powder materials, purity is generally required to be above 99.15%, the main application objects are zinc oxide varistor, ceramic capacitor, ferrite magnetic materials in three categories.
Atmospheric carbon dioxide or water-soluble carbon dioxide reacts easily with Bi2O3 to form bismuth subcarbonate. Bismuth oxide is considered to be an alkaline oxide, which explains its high reactivity with carbon dioxide. However, when an acidic cation such as Si(IV) is introduced into the bismuth oxide structure, the reaction with carbon dioxide does not occur. Bismuth (III) oxide reacts with a concentrated mixture of sodium hydroxide and bromine or with a mixture of potassium hydroxide and bromine to form sodium bismuth or potassium bismuth, respectively.

The Bismuth Oxide industry has experienced demand expectations driven by the rise and the off-season tired stock driven by the seasonal decline in two rounds of the market. Affected by the COVID-19 epidemic and other factors, inventories of manufacturers continue to accumulate, putting pressure on market sentiment. In addition to off-season factors, the weak trend of Bismuth Oxide also reflects the market's concern about the epidemic and some other related enterprises' financial situation.
