| 摘 要： | 利用硝酸铝、尿素和炸药为原料,通过研究配比出一种类似塑性炸药的混合炸药,引爆此混合炸药,爆轰完毕得到了纳米-αAl2O3粉体。对收集到的实验粉体分别进行了高分辨率透射电镜分析、衍射分析和热分析。分析结果表明,用此法所得到的纳米-αAl2O3呈球形,颗粒尺寸分布非常均匀,每个颗粒的大小为35nm左右,晶型为单一的α型。爆轰法合成纳米-αAl2O3具有合成反应速度快、设备简单和易放大产量的优点。

| Abstract: | A mixing explosive was made with a special proportion of aluminum nitrate,carbamide and explosive.It was similar to plastic-type explosive.The nanometer α-aluminum oxide was formed by detonation of the mixing explosive.It was analyzed by means of TEM,XRD and DTA/TGA respectively.The experimentation results proved that the nanometer α-aluminum oxide was spheric,the distribuion of grain size was uniform,with each grain being about 35nm,and the aluminum oxide was αaluminum oxide.The detonation synthesis of nanometer α-Al_2O_3 powder was of such advantages as fast reaction rate,simple equipment and flexibility in enlarging capacity. |
