| 摘 要： | 通过高能球磨法处理Y2O3-Al2O3(yttrium aluminum garnet,YAG)混合粉体,对球磨产物进行煅烧、成型以及烧结,并对固相反应中的物相变化、YAG粉体形貌以及YAG陶瓷密度、力学性能及显微结构进行表征和分析,确定了最佳的球磨时间和粉体煅烧温度.研究表明:经过40h高能球磨,得到的球磨产物具有良好的活性.采用传统固相法制备的YAG粉体,需要在1 500℃煅烧,该方法处理的YAG粉体在1 200℃煅烧2 h,可以得到活性较高的YAG粉体,使粉体的煅烧温度下降了300℃.利用常压烧结在1 550℃烧结坯体2h,得到致密的YAG陶瓷,明显改善了YAG陶瓷制备技术.

| Abstract: | Yttrium aluminum garnet(Y_2O_3-Al_2O_3,YAG) mixtures prepared by a high-energy ball milling were calcined,compacted and sintered.The phase change in the solid-state reaction,the powder morphology and YAG density,the mechanical properties,and the microstructure were characterized and analyzed,and the best combination of milling time and calcination temperature was identified. The results show that the product has good activity after milling for 40 h in a high-energy ball-milling system,in the traditional sol... |
