钇铝石榴石(YAG)透明陶瓷被证明为量子电子学历史上最好的固体激光材料，因为其具有无与伦比的光学、力学和热性能。而在YAG透明陶瓷的整个制备过程中，YAG纳米粉体的团聚性能是影响所制备透明陶瓷最终性能的关键因素之一。以共沉淀法制备的YAG纳米粉体为原料，研究了球磨时间和分散剂Dolapix CE-64对YAG纳米粉体去团聚性能的影响，并通过X射线衍射(XRD)、Zeta电位、激光粒度和扫描电镜(SEM)等一系列表征手段对实验结果进行了表征。实验结果表明，通过添加质量分数为10% 的Dolapix CE-64 、球磨24 h处理对YAG纳米粉体去团聚效果最佳。

Yttrium aluminum garnet (YAG) transparent ceramic has been proved to be one of the best solid-state laser materials in the history of quantum electronics. Its indisputable dominance in solid-state laser application is determined by its unrivalled optical, mechanical and thermal properties. During the fabrication of YAG transparent ceramic, agglomeration of YAG nanopowders can deteriorate the performance of transparent ceramic. YAG nanopowders are prepared by co-precipitation, then deagglomerated by ball milling and adding Dolapix CE-64. YAG nanopowders and its slurry are characterized by X-ray diffraction (XRD), Zeta potential, laser granulometer and scanning electron microscope (SEM). The results show that YAG nanopowders are well deagglomerated by adding 10 percent of Dolapix CE-64 and ball milling of 24 h.
