摘要：

Nano-sized powders of aluminum yttrium garnet (YAG) have been successfully synthesized by a mixed solvo-thermal method at low temperature (300 degreesC) and low pressure (10 MPa). The phase transformation, composition and micro-structural features of the crystalline samples were characterized by X-ray powder diffraction, IR and TEM techniques. It was found that type of solvent, reaction temperature and time were important factors in the YAG synthesis process. X-ray powder diffraction pattern indicated that the pure phase YAG was synthesized in mixed solvent at 300 degreesC. The transmission electron microscopy (TEM) revealed the averaged size of crystallite was 20 nm and well dispersed. Moreover, the mechanism for solvo-thermal crystallization of YAG is proposed based on IR results. (C) 2004 Elsevier B.V. All rights reserved.
