Terbium(III, IV) Oxide
Terbium(III, IV) Oxide, wanda wani lokacin ake kira tetraterbium heptaoxide, yana da dabarar Tb4O7, tushen Terbium ne mai ƙarfi wanda ba ya narkewa sosai a yanayin zafi. Tb4O7 yana ɗaya daga cikin manyan mahaɗan terbium na kasuwanci, kuma shine kawai irin wannan samfurin da ke ɗauke da aƙalla wasu Tb(IV) (terbium a cikin yanayin iskar shaka +4), tare da Tb(III) mafi ƙarfi. Ana samar da shi ta hanyar dumama ƙarfe oxalate, kuma ana amfani da shi wajen shirya wasu mahaɗan terbium. Terbium yana samar da wasu manyan oxides guda uku: Tb2O3, TbO2, da Tb6O11.
