以廉价的硝酸铝和硝酸钇为原料，乙二胺（EDA）溶液为溶剂，采用溶剂热法在温和条件下合成了钇铝石榴石（YAG）粉体。分别以尿素和碳酸氢铵为沉淀剂，采用两种不同的沉淀方法合成氢氧化物前驱体。利用傅里叶变换红外光谱（FT-IR）、X射线衍射（XRD）和透射电子显微镜（TEM）对YAG颗粒的形成进行了研究。TEM结果表明，以碳酸氢铵为沉淀剂，成功地合成了球形YAG粉体。
Yttrium aluminum garnet (YAG) powders were synthesized by a solvothermal method under mild conditions with inexpensive aluminum and yttrium nitrates as the starting materials, and the ethylenediamine (EDA) solution as the solvent. Hydroxide precursors were synthesized by two different precipitating processes, in which urea or ammonium hydrogen carbonate was used as precipitant. The formation of YAG particle was investigated by means of Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD) and transmission electron microscopy (TEM). The TEM results showed that spherical YAG powders were successfully synthesized when ammonium hydrogen carbonate was used as precipitant.
