Daim ntawv thov
Cerium chloride heptahydrate, nyob rau hauv cov ntaub ntawv ntawm crystalline aggregates los yog lub teeb daj pob aggregates, yog cov khoom tseem ceeb rau catalyst, iav, phosphors thiab polishing hmoov. 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. 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. Cerium chloride yog used nyob rau hauv kev lag luam xws li roj av catalysts, automotive tso catalysts, intermediate compounds, thiab lwm yam. Nws kuj yog siv los ua hlau cerium, thiab lwm yam. Cerium chloride yog siv nyob rau hauv industries xws li tshuaj intermediates, cerium ntsev raw cov ntaub ntawv, hard alloy additives, thiab tshuaj. reagents
