Applications:
Bismuth oxide nanoparticles are used in electronics and in the glass and ceramic industries. In electronics, they are applied in capacitors, pressure-sensitive resistors, and solid electrolytes. In ceramics, they help improve material performance. When added to glass, they increase the refractive index and serve as a substitute for lead oxide, making them an excellent alternative to traditional lead glazes.
These nanoparticles are also used as fillers in polymers and rubber, in fireproofing papers, disinfectants, and magnets. Additionally, they have applications in medicine, including artificial bone imaging.
