Bismuth Trioxide (Bi2O3)

Bismuth Trioxide (Bi₂O₃) is the prevalent commercial oxide of bismuth. It is widely used in the industry of Ceramics and Glasses, Rubbers, Plastics, Inks, and Paints, Medical and Pharmaceuticals, Analytical reagents, Varistor, Electronics.

 

A precursor to the preparation of other compounds of bismuth, Bismuth trioxide is used for preparing bismuth salts and manufacturing fireproof paper as chemical analytic reagents. This bismuth oxide can be widely applied in inorganic synthesis, electronic ceramics, chemical reagents, etc., is mainly used for manufacturing ceramic dielectric capacitors and can also be used for manufacturing electronic ceramic elements such as piezoelectric ceramics and piezoresistors.

 

Bismuth Trioxide has specialized uses in optical glass, flame-retardant paper, and, increasingly, in glaze formulations where it substitutes for lead oxides. In the last decade, bismuth trioxide has also become a key ingredient in flux formulations used by mineral analysts in fire assaying.
