掺钕钇铝石榴石(Nd:YAG)多晶透明陶瓷具有良好的化学稳定性、光学性能和耐高温性能,是一种很有前途的激光工作物质.以Al(NO3)·9H2O,Y2O3,Nd2O3,(NH4)2SO4和NH4HCO3为原料,正硅酸乙酯为添加剂,采用共沉淀法制备出分散均匀、团聚程度轻、YAG立方晶相的Nd:YAG纳米前驱体粉末,采用TG/DTA,XRD,FT-IR和TEM等测试手段对Nd:YAG陶瓷材料进行表征.研究结果表明:前驱体粉末在800℃时为无定型态,当温度达到900℃时析出大量的晶体YAlO3(YAP)和少量的YAlO3(YAP),当温度达到1100℃时就全部转化为立方晶相;前驱体纳米粉末中存在轻微的团聚,主要是在1100℃高温时晶粒发生了生长,连接在一起,但是作为团聚整体而言,颗粒分布比较均匀.
