Samarium (III) Oxide
Samarium (III) Oxideyog cov tshuaj sib xyaw nrog cov tshuaj formula Sm2O3. Nws yog ib qho insoluble thermally ruaj khov Samarium qhov chaw haum rau iav, optic thiab ceramic daim ntaub ntawv. Samarium oxide tau nkag mus rau saum npoo ntawm cov hlau samarium nyob rau hauv cov av ntub lossis kub tshaj 150 ° C hauv huab cua qhuav. Cov oxide feem ntau yog xim dawb kom tawm xim daj thiab feem ntau ntsib raws li cov plua plav zoo heev xws li hmoov daj daj, uas yog insoluble hauv dej.
