摘要：

Yttrium aluminum garnet (YAG) precursor was prepared by sol-gel combustion method using ethanol as solvent. Nano-sized YAG powders were obtained by precalcining the precursor at 500 degrees C, and then calcining at different temperatures. The phase formation and characteristics of YAG powders were investigated by means of XRD, TG/DSC and TEM. Pure crystalline YAG phase was obtained at 800 degrees C, without any intermediate phases such as YAlO3 (YAP) and Y4Al2O9 (YAM). Moreover, it was found that the elliptical YAG powder calcined at 900 degrees C for 2 h was well-crystallized with an average size of 30 nm, and had a good dispersity. (C) 2009 Elsevier B.V.
