摘要
通过添加含能前驱体如硝酸锂和硝酸锌,利用爆燃反应合成了新的块状锌锂复合氧化物纳米晶。并用扫描电子显微镜观察了乳化炸药爆燃产物的形貌,通过X射线粉末衍射仪和透射电子显微镜确定了爆燃产物的结构。研究结果表明:锌锂氧化物呈现50 nm～200 nm一次粒径和方块状粒子特征。通过此廉价方法制备的该氧化物肯定了爆燃合成纳米粉体的有效性。
We have synthesized a novel lithium and zinc composite oxide nanoagglomerations via deflagration reaction by adding energetic precursors, such as lithium nitrate and zinc nitrate. The deflagration products of emulsion explosives were characterized by scanning electron microscopy, powder X-ray diffraction and transmission electron microscopy to observe the structures. The lithium and zinc oxides were found with primary particles diameters from 50 nm to 200 nm and a variety of square morphologies. This cheap method to produce the oxides affirmed the validity of deflagration synthesis of nano-size powders.
