Wet methods involve the injection of UF6 into water to form a UO2F2 particulate slurry.
Either ammonia (NH3) or ammonium carbonate ((NH3)2CO3) is added to this mixture and the UO2F2 reacts to produce;
ammonium diuranate (ADU, (NH3)2U2O7)
ammonium uranyl carbonate (AUC, UO2CO3.(NH3)2CO3)
In both cases the slurry is filtered, dried and heated in a reducing atmosphere to pure UO2.
