以廉价的硝酸铝和硝酸钇为原料，廉价的乙醇-水混合溶液为溶剂，采用混合溶剂热法在较温和的条件下合成了钇铝石榴石（YAG）粉体。X射线衍射（XRD）、差热分析（DTA）和透射电子显微镜（TEM）分析表明，合成的粉体为单相YAG，颗粒细小，分散性好，平均粒径为80 nm，粒度分布较窄。此外，还对YAG晶粒的晶化过程进行了讨论。
Yttrium aluminum garnet (YAG) powder was synthesized by a mixed solvothermal method under milder conditions with inexpensive aluminum and yttrium nitrates as the starting materials, and the low-cost ethanol–water mixed solution as the solvent. X-ray diffraction (XRD), DTA and TEM analysis showed that the powder synthesized was single-phase YAG, with well-dispersed fine spherical grains (80nm average) and a relatively narrow grain size distribution. Moreover, the crystallization process of YAG grains was discussed.
