초록
Yttrium aluminum garnet (YAG) has good optical properties and has been widely used in engineering. The preparation ofconventional YAG powder is costly due to its high synthesis temperature, so lowering the synthesis temperature is the mosteffective way to save cost. The ultrafine oxide composite powder was rapidly synthesized using the microwave hydrothermalmethod at a low temperature. The effect of temperature and its performance. Differential thermal analysis and XRD phaseanalysis 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, andparticle size analysis revealed that the microwave hydrothermal reaction temperature was 170 oC, and the high-purityultrafine YAG powder was calcined at 928 oC, which was lower than conventional calcination temperature. The synthesizedultrafine spherical YAG powder had a small particle size and a uniform distribution.
