Nd:YAG透明陶瓷的研究
Research on Transparent Ceramics of Nd:YAG

采用固相反应法制备了NdYAG透明陶瓷，并通过碳铵沉淀法处理Y_2O_3商业原料，进一步提高了Nd:YAG透明陶瓷的透明度. 结果表明：采用高纯的商业原料，通过固相法制备获得的透明陶瓷，在1 064 nm处光线直线透过率可达到74%左右；通过碳铵共沉淀法改良商业Y_2O_3粉体原料的性能，透明陶瓷的透过率可进一步提升，在1 064 nm处光线直线透过率高达78%.
：NdYAG transparent ceramics are prepared by solidstate reaction method in this investigation. And it is found that the transmittance of the Nd:YAG transparent ceramics could be improved by using Y_2O_3 powder prepared by ammonium carbonate precipitation method. The results show that the transparent ceramics with high linear transmittance at 1 064 nm (~74%) could be obtained by using highpurity commercial raw materials. And by using Y_2O_3 powder prepared by ammonium carbonate precipitation method, the linear transmittance of the transparent ceramics could be improved up to 78% at 1 064 nm
