A yellow nanopowder composed of nanoparticles of bismuth oxide. Compared to other nanoparticles, bismuth oxide nanopowder/ nanoparticles are relatively larger.



1-Electronics. Thin films and slurries produced using bismuth oxide nanoparticles in combination with other nanomaterials have been the subject of extensive engineering and physics research in recent years. Many advanced electronics already use such nanomaterials to great advantage, with new applications and traits being uncovered with each passing year.

2- Optic devices. As with many nanoparticles, bismuth oxide nanopowders have seen extensive research and use for their unique optic properties. At such small scales, the particles begin to interact differently with light, heat, and other forms of energy. Bismuth oxide nanoparticles have specifically been researched as an option for targeted medical imaging, including artificial bone imaging and cancer imaging.

3- Lead oxide alternative. Bismuth in general works similarly to lead in numerous applications, but without the toxicity. Similarly, bismuth oxide nanopowders can be used as an alternative to lead oxide in applications where lead isn’t desired for one reason or another. Places where bismuth oxide has partially or wholly replaced lead include ceramics and glass production.
