Precipitation conditions, such as molar ratio of ammonia to uranium, uranium content, ammonium hydroxide content, temperature, rate of adding uranium, etc. , have influences on ADU particle size, its microstructure and the properties of UO2 powder.

• 沉淀条件例如氨铀比,铀浓度,氨水浓度,温度,加料速度等影响着ADU颗粒尺寸和微观结构以及其后UO_2粉末的性质。
