摘　　要：粉体团聚性能是决定Nd：YAG透明陶瓷性能的关键因素之一。本文采用共沉淀法制备Nd：YAG纳米粉体，研究了固含量、磨介／粉体比例、球磨时间和分散剂Dolapix CE-64对去团聚性能的影响，并通过XRD、Zeta电位、激光粒度仪和扫描电镜对实验结果进行了表征。结果表明，料浆固含量45％、CE．64添加量10wt％、10倍磨介球、球磨时间24小时去团聚效果最佳。The agglomeration of Nd：YAG nanopowders had a great influence on the preparation and performance of transparent ceramics. In this paper, Nd：YAG nanopowders were synthesized by co-precipitation and the effects of solid content, milling media/powder ratio, ball milling time and the Dolapix CE-64 dispersant on the deagglomeration were studied. After ball milling, the Nd：YAG nanopowders were characterized by the XRD, Zeta potential, laser granulometer and SEM. The results showed that the Nd：YAG nanopowders were well deagglomerated by adding 45 percent of solid, 10 times of ball to water, 10 percent of CE-64 and ball milling of 24 hours.
