Overview Of Bismuth Bi Powder

Bismuth Bi Powder, or bismuth powder, is a powdered material made of metallic bismuth, usually silver white or slightly light blue metallic luster. Bismuth is relatively stable in air and water at room temperature but can react with oxygen, halogens, and sulfur when heated.

Applications of Bismuth Bi Powder

 

Sensors: Bismuth, due to its unique physical and chemical properties, has also been applied in sensor technology, especially in temperature sensing and resistance sensing.

 

Giant magnetoresistance field: Bismuth is also applied in giant magnetoresistance materials, which undergo significant changes in resistance when the magnetic field changes. It is used to manufacture magnetic heads, magnetic recording media, and magnetic sensors.

 

Pharmaceutical industry: Bismuth, as a safe "green metal," has certain applications in the pharmaceutical industry, especially in the electrochemical detection of trace heavy metals. Bismuth film electrodes have a trend to replace the traditional detection electrode of mercury.

 

Preparation of nanomaterials: Bismuth nanomaterials, including nanowires, nanotubes, nanoflowers, etc., have wide applications in scientific research and industrial fields, especially in electronics, optics, and catalysis.

 

Other fields: Bismuth powder can also be used as a raw material for pigments, glass, ceramics, and other products, as well as an additive for fireproof materials.
