摘要
研究了用尿素溶液作沉淀剂在ＵＯ２（ＮＯ３）２（ＵＮＨ）溶液中制备重铀酸铵（ＡＤＵ）沉淀物的初步工艺。获得了反应温度、ＵＮＨ浓度、尿素加入量及反应时间对ＡＤＵ沉淀的影响规律。采用该工艺，制得了性能良好的ＡＤＵ粉末。
he paper introduces the basic technical research of ADU precipitation which is prepared in UO2(NO3)2 and urea solution.The effects of reaction temperature,UNH concentration,urea amounts and reaction period on the ADU precipitation is researched, and ADU powder with good technological properties is prepared.
