I-Cerium oxide (CeO2), umgubo otyheli okhanyayo kwiqondo lobushushu begumbi, yeyona oxide izinzileyo ye-earth element enqabileyo i-cerium. Isetyenziswa ngokubanzi njengezongezo kwishishini leglasi, izinto zokupolisha, izongezo zepeyinti, izinto ezinqabileyo zomhlaba ezikhanyayo, njl.
Inkampani ye-WONAIXI ivelise i-cerium oxide iminyaka engaphezu kweshumi kwaye inokubonelela abathengi ngemveliso ephezulu ye-cerium oxide kunye nexabiso lokukhuphisana.
