Dab tsi yog preaseymium (III, iv) oxide siv rau?
Tus lej (III, IV) Oxide muaj ntau daim ntawv thov muaj peev xwm ua rau muaj kev sib txuas lus nrog cov neeg muaj peev xwm xws li sodium lossis kub kom txhim kho kev ua haujlwm catalanytic.
Praseodymium (III, IV) Oxide siv rau hauv cov xim hauv cov iav, optic thiab ceramic thiab ceramic lag luam. Cov iav preodymium-doped iav, hu ua downymium iav yog siv nyob rau hauv vuam, blacksmithing, thiab iav tshuab tsom iav vim nws cov khoom thaiv ntawm infrariated hluav taws xob. Nws tau ua haujlwm nyob rau hauv lub xeev ruaj khov hluav taws xob synthesis ntawm preaseymium molybdenum oxide, uas yog siv ua semiconductor.
