Abstract

Abstract

The precipitation of ammonium uranyl carbonate（AUC） use NH₃ and CO₂ gas by the contrary feeding method is investigated in this report.The influences factor such as reaction temperature,feed concentration,feeding speed has been studied.The experiment shows that controlling the reaction temperature in 60℃～70℃,feed concentration in 200g/L,feeding speed in 40L/h is feasible.The fluorine content of AUC crystal is under 1000μg/g,the bulk density of AUC is in 0.8 g/cm³～1.0g/cm³,and it has the excellent flow-ability.
