摘要

采用固态反应烧结和真空烧结两种方法制备了Nd:YAG陶瓷。比较了烧结陶瓷的密度、显微组织、平均晶粒尺寸、残余孔隙率、透光率等。固态反应烧结制备的Nd:YAG陶瓷比共沉淀纳米粉体真空烧结制备的Nd:YAG陶瓷具有更高的透光率，但仍低于单晶。讨论了提高Nd:YAG陶瓷光学质量的可能途径。

Comparison of Nd:YAG optical ceramics produced by different sintering routes

Nd:YAG ceramics were fabricated by solid-state reactive sintering of commercial powders and vacuum sintering of custom made co-precipitated nanopowders. The densities, microstructure, average grain size, residual porosity, optical transmittances of the sintered ceramics were compared. Nd:YAG ceramics produced by solid-state reactive sintering possess higher transmittance compared to vacuum-sintered ceramics from co-precipitated nanopowders, which is however still lower than that of single crystals. The possible ways to improve optical quality of Nd:YAG ceramics are discussed.
