Powders prepared under different fuel combustion conditions were investigated by XRD and TEM. The results show that, under slightly rich fuel condition, the product powders contain less impurity phases, and powders prepared by the glycine-nitrate combustion contain far less impurity phases and have smaller particle sizes than those prepared by solid-state reaction method or acrylamide polymerization technique. 关 键 词：氨基乙酸硝酸盐燃烧方法 固态反应法 丙烯酰胺聚合技术 相位构造 LAGAO3
