Cerium Oxide Nanoparticles

Powder and Dispersion - Product Number 09817

Ceria (cerium oxide, CeO2) nano abrasive powder finds applications in the precision polishing of most semiconductor substrate materials including silicon, sapphire, GaAs, etc. Ceria nano abrasive powder has been shown to not only demonstrate tremendous advantages in the planarization process of most semiconductor materials but glassy materials employed in photonic applications as well.


Ceria powder is designed based on application-specific needs as stated by the customer, in scaled quantities with a mean particle diameter of 8 nm. It can be designed in various form factors: powder, aqueous pH modified dispersion, and organic liquid dispersion. Custom form factors are available upon request.
