Abstract

Yttrium aluminum garnet (YAG) has good optical properties and has been widely used in engineering. The preparation of conventional YAG powder is costly due to its high synthesis temperature, so lowering the synthesis temperature is the most effective way to save cost. The ultrafine oxide composite powder was rapidly synthesized using the microwave hydrothermal method at a low temperature. The effect of temperature and its performance. Differential thermal analysis and XRD phase analysis showed the mixed solution of Al(NO3)3 and Y(NO3)3 at pH=9 and C(Al3+)=0.42 mol·L−1. SEM, zeta potential, and particle size analysis revealed that the microwave hydrothermal reaction temperature was 170 oC, and the high-purity ultrafine YAG powder was calcined at 928 oC, which was lower than conventional calcination temperature. The synthesized ultrafine spherical YAG powder had a small particle size and a uniform distribution.
