Daim ntawv thov

Cerium Oxide, tseem hu ua Ceria, yog dav siv hauv iav, ceramics thiab catalyst manufacturing. Hauv kev lag luam iav, nws yog
suav hais tias yog qhov zoo tshaj plaws iav polishing tus neeg saib xyuas rau precision kho qhov muag polishing. 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 tawm ultra violet lub teeb yog siv nyob rau hauv lub
kev tsim cov iav kho mob thiab aerospace windows. Nws kuj tseem siv los tiv thaiv cov polymers los ntawm kev tsaus ntuj hauv lub hnub ci thiab txhawm rau txo cov xim ntawm cov iav TV. 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.
