I-Cerium oxide (CeO2), impushana ephuzi ekhanyayo ekushiseni kwegumbi, iyi-oxide ezinzile ye-cerium element yomhlaba engavamile. Isetshenziswa kabanzi njengezithasiselo embonini yengilazi, izinto zokupholisha, izithasiselo zikapende, izinto ezingavamile ze-luminescent, njll, futhi njengezinto zokusetshenziswa zokwenziwa kwensimbi ye-cerium.
Inkampani ye-WONAIXI ikhiqize i-cerium oxide iminyaka engaphezu kweshumi futhi ingahlinzeka amakhasimende ngemikhiqizo yekhwalithi ephezulu ye-cerium oxide kanye nenani lokuncintisana.
