Cerium (III) Carbonate siv rau dab tsi?
Cerium(III) Carbonate siv rau hauv kev tsim cov cerium(III) chloride, thiab hauv cov teeb incandescent. Cerium Carbonate kuj siv rau hauv kev ua cov catalyst thiab iav, thiab tseem yog cov khoom siv raw rau kev tsim lwm cov Cerium compounds. Hauv kev lag luam iav, nws suav hais tias yog tus neeg sawv cev polishing iav zoo tshaj plaws rau kev polishing optical precision. Nws kuj siv los tshem tawm cov xim iav los ntawm kev khaws hlau hauv nws lub xeev ferrous. Lub peev xwm ntawm Cerium-doped iav los thaiv lub teeb ultra violet yog siv rau hauv kev tsim cov khoom siv kho mob iav thiab cov qhov rai aerospace. Cerium Carbonate feem ntau muaj tam sim ntawd hauv feem ntau ntawm cov ntim. Ultra high purity thiab cov khoom xyaw purity siab txhim kho ob qho tib si optical zoo thiab muaj txiaj ntsig raws li cov qauv kev tshawb fawb.
Los ntawm txoj kev, ntau daim ntawv thov lag luam rau cerium suav nrog metallurgy, iav thiab iav polishing, ceramics, catalysts, thiab hauv phosphors. Hauv kev tsim hlau nws yog siv los tshem tawm cov pa oxygen dawb thiab sulfur los ntawm kev tsim cov oxysulfide ruaj khov thiab los ntawm kev khi cov ntsiab lus tsis xav tau, xws li txhuas thiab antimony.
