Bismuth Oxide (Bi2O3)
- Description
Description
Bismuth oxide (Bi2O3) appears as yellow power or crystals. It is also known as Bismuth trioxide, Bismuth(III) oxide, or Bismite.
Bismuth oxide is the starting point for most bismuth chemistry. It has end-use across hundreds of industries and specialties. Notable uses include:
- Bismuth chemistry. Many other derivatives of bismuth are manufactured from a starting point of bismuth oxide, thanks to its easy availability and chemical versatility.
- Medical devices. Used in a number of dental materials to improve x-ray opacity.
- The conductivity of bismuth oxide makes it a key component in a number of components and materials used in electronics, including superconductors, semiconductors, and more.
- Energy storage. Bismuth oxide is a potential core component of solid-oxide fuel cells. Initial research suggests high value as an ionic conductor due to its electrical and thermal properties.
- Bi2O3 is also used in fireworks production and general pyrotechnics, where is has replaced the more hazardous red lead.
