掺钕钇铝石榴石（Nd：YAG）多晶透明陶瓷具有容易制造、成本低、光学性能好、热导率高等优点，是一种很有前途的激光工作物质。以AI（N03）·9H2O，Y2O3，Nd2O3，（NH4）2SO4和尿素为原料，正硅酸乙酯为添加剂，采用均相沉淀法制备出分散均匀、纯YAG立方晶相的Nd：YAG纳米前驱体粉末。采用XRD、FT-IR、TEM等测试手段对前驱体粉末进行表征。研究结果表明：Nd：YAG前驱体粉末在800℃时为无定型态，当温度达到890℃时析出大量的中间相YAlO3（Y=AP）和少量的Y3Al5O5（YAG），当温度达到1000℃时就全部转化为YAG立方晶相。

Transparent polycrystalline Y3A I2O12(YAG) ceramics with easy to manufacture, low cost, good optical performance, high thermal conductivity is becoming a new laser host material. The Nd:YAG precursor powders with loosely dispersed, slightly agglomerated and YAG pure cubic crystal phase were synthesized by the homogeneous precipitation method, using Nd203, Y2O3, AI(NO3)3·9H2O, (NH4)2SO4 and urea as raw materials, TEOS as sintering additive. The Nd:YAG ceramic materials were characterized by the XRD, FT-IR,TEM. The results showed that Nd:YAG precursor powder at 800 ℃ without fixed pattern, when the temperature reached 890 ℃ precipitation amount of intermediate phase YAIO3 (YAP) and a small amount of Y3AI5O5 (YAG), when the temperature reached 1000℃ was transformed into YAG cubic phase.
