Cerium (III) Carbonate siv rau dab tsi?
Cerium (III) Carbonate yog siv rau hauv kev tsim cov cerium (III) chloride, thiab nyob rau hauv incandescent teeb.Cerium Carbonate kuj yog siv nyob rau hauv ua auto catalyst thiab iav, thiab kuj yog raw cov ntaub ntawv rau ua lwm yam Cerium tebchaw.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.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.Cerium Carbonate feem ntau muaj tam sim ntawd nyob rau hauv feem ntau ntim.Ultra siab purity thiab siab purity compositions txhim kho ob qho tib si kho qhov muag zoo thiab muaj txiaj ntsig zoo raws li cov qauv kev tshawb fawb.
Los ntawm txoj kev, ntau daim ntawv thov kev lag luam rau cerium muaj xws li metallurgy, iav thiab iav polishing, ceramics, catalysts, thiab phosphors.Hauv kev tsim steel nws yog siv los tshem tawm cov pa dawb thiab sulfur los ntawm kev tsim cov oxysulfide ruaj khov thiab los ntawm kev khi cov kab tsis zoo, xws li txhuas thiab antimony.
