The Applications of Bismuth Oxide

The U.S. and its allies plan to impose sanctions on more Russian industries and supply chains.

The US government representatives recently visited Europe to consult with allies on strengthening and enforcing sanctions to punish Russia. They also plan to take action to disrupt their critical supply chains.

The US government claims that the sanctions imposed on Russia since the invasion began on February 24 have proved extremely effective, plunging Russia into a financial crisis. The sanctions include a freeze on the Russian central bank’s foreign exchange assets, a ban on hard currency transactions by major Russian banks and wealthy individuals, and export restrictions on advanced semiconductors and other technologies. The sanctions have weakened the Russian economy and left the Kremlin with fewer resources.

The volatile international political situations will continue to affect the markets and prices of many commodities like the Bismuth Oxide.

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.

Europe has been facing the gas shortage problem since the second half of 2021. The worsening situation in Russia and Ukraine has reduced Russian gas shipments to Europe, leading to a doubling of European gas prices. Energy shortages have sent electricity prices soaring. For these reasons, it is predicted that the price of the Bismuth Oxide will continue to increase.
