Abstract
Nano-sized powders of aluminum yttrium garnet (YAG) have been successfully synthesized by a mixed solvo-thermal method at low temperature (300 °C) 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 °C. 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.
