Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa).
Terbium(IV) oxide is an inorganic compound with a chemical formula TbO2. It can be produced by oxidizing terbium(III) oxide by oxygen gas at 1000 atm and 300 °C.
Terbium(IV) oxide starts to decompose at 340 °C, producing Tb5O8 and oxygen.
