纳米氧化铝的制备实验研究

Experiment study of nanometer aluminum oxide

讲述了用九水硝酸铝盐粉体与炸药黑索金粉体按一定质量比搅拌混合形成的“混合炸药”爆轰得到纳米γ型氧化铝的实验研究.并对爆轰得到的粉体利用X光衍射仪、透射电镜、扫描电镜和热分析仪器进行了实验检测分析.分析结果证明了用此爆轰法所得到的氧化铝的晶型为γ型,颗粒尺寸大小为纳米级,平均晶粒度为23 nm,颗粒为球形.

Experiments were carried out to study the synthesis of nanometer γ aluminum oxide by the mixture detonation of nine water aluminum nitrate and RDX with a given quality ratio.The detonation product was analysed by XRD,TEM,SEM,and DTA/TG respectively.The results prove that the detonation product is nanometer and spherical aluminum oxide,and the average is 25?nm.The product is γ-aluminum oxide.
