Kev siv Cerium oxide
1. Cerium Oxide, tseem hu ua Ceria, yog dav siv hauv iav, ceramics thiab catalyst manufacturing.
2. Hauv kev lag luam iav, nws raug suav tias yog iav polishing tus neeg saib xyuas zoo tshaj plaws rau kev kho qhov muag polishing.
3. Nws kuj yog siv los decolorize iav los ntawm kev khaws cov hlau hauv nws lub xeev ferrous.Lub peev xwm ntawm Cerium-doped iav los thaiv lub teeb ultraviolet yog siv hauv kev tsim cov iav kho mob thiab lub qhov rais aerospace.
4. Nws kuj yog siv los tiv thaiv polymers los ntawm darkening nyob rau hauv tshav ntuj thiab mus suppress discoloration ntawm TV iav.
5. Nws yog siv rau cov khoom siv kho qhov muag los txhim kho kev ua haujlwm.High purity Ceria kuj siv nyob rau hauv phosphors thiab dopant rau siv lead ua.
