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 860degC. Soluble in acids but insoluble when water. This can be easily reduced 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. But, if Si(IV) or another acidic cation is introduced to bismuth oxide structures, it does not react with carbon dioxide. The concentration of sodium hydroxide, bromine or a mixture thereof will form bismuth (III), or potassium bismuth.

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 materials, and as catalyst. A purity level of 99.15% is required for bismuth dioxide, which is an important ingredient 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, red glass compounding agents, and so forth.
It is used extensively in electronics, chemicals, glass, plastic, ceramic glaze, and other industries such as catalysts, electronic ceramic powder, magnet materials magnetic materials high-temperature superconducting material, metal materials, photoelectric materials.
