摘 要：We reported on the successful synthesis of the Nd:YAG （Nd:Y3Al5O12） nano-powders by using urea as the precipitant with the microwave assisted homogeneous precipitation （MAHP） method. The different microstructural characteristics of the Nd:YAG nano-powders were affected by the concentrations of （Y3++Nd3+） and Al3+ （[Y3++Nd3+]=0.06 mol/L, [Al3+]=0.1 mol/L）, aging time （6 d） and aging condition （in vessel）. The optimum microstructural characteristics of the high quality Nd:YAG nano-powders leading to transparent Nd:YAG ceramics including the pure YAG phase, the smallest crystallite size, a uniform crystallite size distribution, less density defects, uniform micro-components and the proper molar ratio of （Y3++Nd3+） and Al3+ （0.6148） were discussed.
