Pages: 86-88
Year: Issue:  1
Journal: Chinese Journal of Energetic Materials

Keyword:  军事化学与烟火技术纳米粉体喷射沉淀法α-Al2O3;
Abstract: 以NH<,3>·H<,2>O和Al<,2>(SO<,4>)<,3>,为原料,通过喷射沉淀法制备了Al<,2>O<,3>前驱体--水合氧化铝(AIOOH),将该前驱体洗涤、干燥、煅烧,获得了窄分布的纳米α-Al<,2>O<,3>粉体.采用XRD、红外光谱和激光粒度分析等测试方法对产物进行表征,结果表明,最后得到目标产物为α-Al<,2>O<,3>,平均粒径为30.9 nm,粒径范围30.1~32.3...
