Details
Production
Uranium dioxide is produced by reducinguranium trioxide with hydrogen.
UO3 + H2 → UO2 + H2O at 700 °C (970 K)
This reaction takes part in the reprocessing of nuclear fuel and enrichment of uranium for nuclear fuel.
Structure
The solid is isostructural with (has the same structure as) fluorite (calcium fluoride). In addition, the dioxides of cerium, plutonium and neptunium have the same structures. No other elemental dioxides have the fluorite structure.
Oxidation
Uranium dioxide is oxidized in contact with oxygen to the triuranium octaoxide.
3 UO2 + O2 → U3O8 at 700 °C (970 K)
The electrochemistry of uranium dioxide has been investigated in detail as the galvanic corrosion of uranium dioxide controls the rate at which used nuclear fuel dissolves. See the spent nuclear fuel page for further details. Water increases the oxidation rate of plutonium and uranium metals
