How do you define it?
Bismuth Oxide Powder
?
The most popular bismuth compound is the Bi2O3 Bismuth Oxide Powder. It is a functional material with advanced functional properties that has exceptional dielectric and oxygen fluidity.
There are two types of pure bismuthtrioxide: a and b. Yellow monoclinic crystal of the a type has an 8.9 relative density and a melting points of 825degC. Solventible in acids, but insoluble when alkali is added. Bright yellow to orange cubic crystal, relative density 8.55, melting temperature 860°C. Soluble in acids but insoluble when water. Reduced easily to metallic bismuth using hydrogen and hydrocarbons.
Here are some of the key features
Bismuth Oxide powder
Bismuth dioxide is an important additive for electronic ceramic material. Its purity must be at least 99.15%. Main application objects include zinc oxide varistor, ceramic capacitor and ferrite magnetic materials.
Water-soluble or atmospheric carbon dioxide can react easily with bi2O3 to make bismuthsubcarbonate. Bismuth dioxide is an alkaline oxide which accounts for its high reactivity to carbon dioxide. The reaction with carbon dioxide does not take place if an acidic compound such as Si(IV), enters the bismuth oxide structure. The concentration of sodium hydroxide, bromine, or a mixture thereof with potassium hydroxide is what forms bismuth (III).

Bismuth Oxide powder uses
Useful for making bismuth sodium salt. Also used in electronic ceramic materials, as photoelectric material, electrodelyte material or high-temperature superconducting material, and catalyst. A purity level of 99.15% is required for bismuth dioxide, which is used as an additive in electronic ceramics powder materials. Zinc oxide varistors, ceramic capacitors and ferrite magnet materials are the main uses. Glaze rubber compounding agent is also used, as medicine compounding agent and red glass compounding agents.
It is used extensively in electronics, chemicals, plastics industry, glass industry and ceramic glaze industries.
