Kev siv cerium carbonate
cerium carbonate 99.99% tsis tshua muaj lub ntiaj teb, feem ntau yog siv rau hauv kev ua nws pib catalyst thiab iav, thiab kuj yog ib tug 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.
