摘　　要：本文采用共沉淀法和溶胶-凝胶法成功合成了1at.%和5at.%的Nd:YAG纳米粉体,并采用TG-DTA、XRD及SEM对前驱体粉体进行表征,最后采用真空热压烧结工艺制得Nd:YAG多晶陶瓷,并对陶瓷晶粒进行了形貌分析.根据实验结果,找出了获得多晶陶瓷的较优配方和影响Nd:YAG陶瓷材料透光度的因素.In this work, 1at. % and 5at. %Nd：YAG nano-meter powders were obtained in chemical co-precipitation method and sol-gel method. And the Nd： YAG precursor powders were characterized by TG-DTA,XRD and SEM. At last, polycrystal Nd：YAG powders were sintered under vacuum atmosphere for cermics, in addition, ceramics grains were represented by SEM. Finally, it has found out that the optimum method of fabricating polycrystal Nd： YAG ceramics, and factors influencing on optical transmittance of Nd： YAG ceramics laser materials.
