Abstract
Nd3xY3−3xAl5O12 (Nd:YAG) powders with high uniformity were synthesized by reverse-titration co-precipitation method. The precipitation formation process and dispersion mechanism of Nd:YAG precursor in co-precipitation process were analyzed, and the influence of the preparation technology on the dispersion of powders was explored by adjusting the concentration of precipitator, alcohol-water solvent and ratio of composite dispersant. In addition, through the analysis of the precursor calcination process, combined with SEM and particle size analysis, it is shown that, under optimum processing conditions, the powders have excellent particle uniformity, narrow particle size distribution and appropriate crystal size when calcined at 1150 °C for 2 h.Keywords
