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