中文摘要：
采用水热法制备了中空短棒状纳米Fe2O3，并用超声分散法将其与纳米Al颗粒复合为单金属氧化基超级铝热剂．利用X射线粉末衍射（XRD）、傅里叶变换红外（FTIR）光谱、扫描电镜及能量散射光谱仪（SEM—EDS）对样品进行表征．并运用差示扫描量热法（DSC）对比研究了超级铝热剂Al／Fe2O3、Al粉和纳米Fe2O3对环三亚甲基三硝胺（RDX）热分解特性的影响．结果表明：超级铝热剂的加入改变了RDX的热分解过程，并加剧了RDX的-二次气棚反应：随着超级铝热剂含量的增加，RDX的分解峰峰形发生了明显的改变：Al／Fe2O3、Al粉和Fe2O3对RDX热分解的作用主要表现为二次分解峰逐渐明显且峰温降低．
英文摘要：
Hollow Fe2O3 nanorods were prepared using a hydrothermal method, and were then combined with AI nanoparticles to form superthermite AI/Fe2O3 by ultrasonic mixing. Fe2O3 and AI/Fe2O3 were characterized using X-ray powder diffraction （XRD）, Fourier-transform infrared （FTIR） spectroscopy, and scanning electron microscopy-energy dispersive spectroscopy （SEM-EDS）. The effects ofAI/Fe2O3, AI, and nano-Fe2O3powders on the thermal decomposition of cyclotrimethylene trinitramine （RDX） were investigated using differential scanning calorimetry （DSC）. The results show that the superthermite All Fe2O3 affects the thermal decomposition of RDX and greatly enhances its secondary gas-phase reaction. The shapes of the main RDX decomposition peaks changed with increasing superthermite content. The main influences of superthermite AI/Fe2O3, AI nanopowders, and Fe2O3 nanorods on the thermal decomposition of RDX are that the secondary decomposition peaks become distinct and the peak temperature decreases.
