Preparation and Properties of Nd-doped Yttrium Aluminum Garnet Ceramics

以Al2O3、Y2O3、Nd2P3为起始原料,用固相合成方法在1500℃、2h条件下合成了掺钕钇铝石榴石(1.1at.%Nd:YAG)粉料.研究表明,在固相反应过程中,首先形成中间相Y4Al2O9(YAM)、YAlO3(YAP)而最终形成单相Y3Al5O12(YAG).将上述粉料经等静压成型并在低真空状态下于1750℃烧结3h,获得呈半透明状态的Nd:YAG陶瓷,其相对密度达到98.68%,显微结构均匀,荧光性能与0.9at% Nd:YAG单晶材料相近.
