1. Creium ox oxide, tseem hu ua Ceria, yog siv dav hauv khob, ceramics thiab catalyst kev tsim khoom.
2.Hauv kev lag luam iav, nws tau suav tias yog qhov ua tau zoo tshaj plaws iav polishing tus neeg sawv cev rau precision kho qhov muag polishing.
3. Nws tseem siv los daws teeb lub khob los ntawm kev khaws cov hlau hauv nws lub xeev ferrous. Lub peev xwm ntawm cov iav cerium-doped los thaiv cov teeb Ultra violet lub teeb yog siv hauv kev tsim khoom ntawm cov iav iav thiab aerospace qhov rais.
4. Nws tseem siv los tiv thaiv cov polymers ntawm tsaus ntuj hauv lub hnub ci thiab txhawm rau txhawm rau tshem tawm cov iav TV.
5. Nws tau thov rau cov khoom siv kho qhov muag kom txhim kho kev ua tau zoo. Muaj kev huv huv ceria tseem siv hauv phosphors thiab dopant rau siv lead ua.
