Terbium(III,IV) oxide, occasionally called ' tetraterbium heptaoxide', has the formula TbO, though some texts refer to it as TbO. There is some debate as to whether it is a discrete compound, or simply one phase in an interstitial oxide system. TbO is one of the main commercial terbium compounds, and the only such product containing at least some Tb(IV) (terbium in the +4 oxidation state), along with the more stable Tb(III). It is produced by heating the metal oxalate, and it is used in the preparation of other terbium compounds. Terbium forms three other major oxides: TbO, TbO, and TbO.
Terbium(III) oxide, also known as terbium sesquioxide, is a sesquioxide of the rare earth metal terbium, having chemical formula . It is a p-type semiconductor when doped with calcium, and may be prepared by the reduction of in hydrogen at 1300 °C for 24 hours.
It is a p-type semiconductor.
It is a basic oxide and easily dissolved to dilute acids, and then almost colourless terbium salt is formed.
TbO + 6 H → 2 Tb + 3 HOThe crystal structure is cubic and the lattice constant is a = 1057 pm.
Terbium oxide may refer to either of the following:
- Terbium(III) oxide, TbO
- Terbium(III,IV) oxide, TbO
