Terbium Oxide Powder The terbium oxide (III, IV), called occasionally tetraterio heptoxide, has the formula Tb4O7, although some texts refer to it as TbO1.75. There is some discussion about whether it is a discrete compound or simply a phase of an interstitial oxide system. Tb4O7 is one of the main commercial compounds of the terbium and the only product that contains at least a little bit of Tb (IV) (terbium in the oxidation state +4), together with the more stable Tb (III). It is produced by heating the metal oxalate and is used in the preparation of other compounds based on terbium. The terbium forms three other main oxides: Tb2O3, TbO2, and Tb6O11.
