Terbium (III, IV) Oxide
Terbium (III, IV) Oxide, qee zaus hu ua tetraterbium heptaoxide, muaj cov qauv Tb4O7, yog ib qho tsis zoo thermally ruaj khov Terbium qhov chaw.Tb4O7 yog ib qho ntawm cov khoom lag luam tseem ceeb terbium, thiab tsuas yog cov khoom lag luam uas muaj tsawg kawg yog qee qhov Tb(IV) (terbium hauv +4 oxidation. xeev), nrog rau qhov ruaj khov dua Tb(III). Nws yog tsim los ntawm cua sov cov hlau oxalate, thiab nws yog siv nyob rau hauv kev npaj ntawm lwm yam terbium tebchaw. Terbium tsim peb lwm cov oxides loj: Tb2O3, TbO2, thiab Tb6O11.
