Effect of Sulfate Ions on YAG Powders Synthesized by Microwave Homogeneous Precipitation Xu Hongyan1,Wang Jieqiang1,Yue Yunlong1,Wang Yong1 (1.School of Materials Science and Engineering, Jinan.... The results show that sulfate ions influence the dispersion, composition and morphology of the YAG precursors. The addition of moderate sulfate ions can produce YAG powders with nano size and excellent......
