Synthesis of Yttrium Aluminium Garnet (YAG) Nano-sized Powders by Mixed Solvo-thermal Method

Ji Wang

Abstract

Polycrystalline nano-sized powders of aluminium yttrium garnet (YAG) were synthesized by a mixed solvo-thermal method at low temperature(300℃) and low pressure (10MPa). The phase transformation, composition and micro-structural features of the final products were characterized by X-ray powder diffraction, IR, BET, and TEM techniques. X-ray powder diffraction patterns indicated that pure phase YAG powder was synthesized in the mixed solvent at lower temperature. The transmission electron microscopy (TEM) revealed the averaged size of crystallite was 20nm and well dispersed. The mechanism of YAG formation in the hydrothermal condition was investigated based on the results.
