摘要
采用固相反应烧结法制备透明Nd∶YAG激光陶瓷。研究了助烧剂对Nd∶YAG微观结构和透过率的影响。当助烧剂SiO2的添加量w（SiO2）=0.3%～0.8%时,样品具有较好的微观结构,SiO2添加量w（SiO2）=0.5%时,波长1 064nm处的透过率为68%。同时添加MgO与SiO2助烧剂时,可进一步改善微观结构和增加透过率,MgO添加量w（MgO）=0.5%时,波长1 064nm处的透过率可达到75%。此外,通过比较干压成型和等静压成型方式发现,采用等静压成型方式可获得更好的微观结构和透过率。
The solid-state reaction sintering method is used to preprare transparent Nd∶YAG laser ceramic.The influence of sintering aids on the microstructures and transmittance of Nd∶YAG are studied.When the weight percentage of SiO2 is between 0.3and 0.8wt%,the sample has better microstructures,transmittance is up to 68% at 1 064 nm wavelength with 0.5wt% SiO2 added.If 0.5wt% MgO is simultaneously added,the transmittance at 1 064 nm wavelength is up to 75%.Additionally,compared with mechanical pressing,the Nd∶YAG ceramic has better microstructures and transmittance by using isostatic pressing.
