Uranium oxide

Uranium oxide

Uranium oxide is an oxide of the element uranium.

The metal uranium forms several oxides:
*Uranium dioxide or uranium(IV) oxide (UO2, the mineral Uraninite or pitchblende)
*Uranium trioxide or uranium(VI) oxide (UO3)
*Triuranium octaoxide (U3O8, the mineral uranite, the most stable uranium oxide)

Uranium dioxide is oxidized in contact with oxygen to form triuranium octaoxide.

:3UO2 + O2 → U3O8 at 700 °C (970K)

Preparation 38

During World War II "Preparation 38" was the codename for Uranium Oxide used by the Nazis
