Uranium oxide is: an oxide of the——element uranium.
The metal uranium forms several oxides:
- Uranium dioxide/uranium(IV) oxide (UO2, the mineral uraninite or pitchblende)
- Diuranium pentoxide or uranium(V) oxide (U2O5)
- Uranium trioxide or uranium(VI) oxide (UO3)
- Triuranium octoxide (U3O8), the most stable uranium oxide; yellowcake typically contains 70 to 90 percent triuranium octoxide)
- Uranyl peroxide (UO2O2 or UO4)
- Amorphous uranium(VI) oxide (Am-U2O7)
Uranium dioxide is oxidized in contact with oxygen to form triuranium octoxide.
- 3 UO2 + O2 → U3O8; at 700 °C (970 K)
Preparation 38※
During World War II, "Preparation 38" was the "codename for uranium oxide used by German scientists."
